Resorcinol BP Ph Eur Grade Specifications
Ph Eur
C6H6O2 --- 110.1 --- CAS 108-46-3

DEFINITION
Resorcinol contains not less than 98.5 per cent and not more than the equivalent of 101.0 per cent of benzene-1,3-diol, calculated with reference to the dried substance.

CHARACTERS
A colourless or slightly pinkish-grey, crystalline powder or crystals, turning red on exposure to light and air, very soluble in water and in alcohol.

IDENTIFICATION
A. Melting point:109C to 112C.
B. Dissolve 0.1 g in 1 ml of water add 1 ml of strong sodium hydroxide solution and 0.1 ml of chloroform, heat and allow to cool. An intense, deep-red colour develops which becomes pale yellow on the addition of a slight excess of hydrochloric acid.
C. Thoroughly mix about 10 mg with about 10 mg of potassium hydrogen phthalate, both finely powdered. Heat over a naked flame until an orange-yellow colour is obtained. Cool and add 1 ml of dilute sodium hydroxide solution and 10 ml of water and shake to dissolve. The solution shows an intense green fluorescence.

TESTS
Solution S: Dissolve 2.5 g in carbon dioxide-free water R and dilute to 25 ml with the same solvent.
Appearance of solution: Solution S is clear and not more intensely coloured than reference solution and remains so when heated in a water-bath for 5 min.
Acidity or alkalinity: To 10 ml of solution S add 0.05 ml of bromophenol blue solution. Not more than 0.05 ml of 0.1 M hydrochloric acid or 0.1 M sodium hydroxide is required to change the colour of the indicator.
Related substances: To pass the test
Pyrocatechol: To 2 ml of solution S add 1 ml of ammonium molybdate solution and mix. Any yellow colour in the solution is not more intense than that in a standard prepared at the same time in the same manner using 2 ml of a 0.1 g/l solution of pyrocatechol.
Loss on drying: Not more than 1.0 per cent, determined on 1.00 g of powdered substance by drying in a desiccator for 4 h.
Sulphated ash: Not more than 0.1 per cent, determined on 1.0 g.

ASSAY
Dissolve 0.500 g in water and dilute to 250.0 ml with the same solvent. To 25.0 ml of the solution in a ground-glass-stoppered flask add 1.0 g of potassium bromide, 50.0 ml of 0.0167 M potassium bromate, 15 ml of chloroform and 15.0 ml of hydrochloric acid. Stopper the flask, shake and allow to stand in the dark for 15 min, shaking occasionally. Add 10 ml of a 100 g/l solution of potassium iodide, shake thoroughly, allow to stand for 5 min and titrate with 0.1 M sodium thiosulphate, using 1 ml of starch solution R as indicator.
1 ml of 0.0167 M potassium bromate is equivalent to 1.835 mg of C6H6O2.

Resorcinol USP Grade Specifications
C6H6O2 110.11
1,3-Benzenediol
Resorcinol [CAS 108-46-3].

Resorcinol contains not less than 99.0 percent and not more than 100.5 percent of C6H6O2, calculated on the dried basis.

Identification:
A: Infrared Absorption 197K NOTE—If necessary to recrystallize, dissolve in dehydrated alcohol.]
B: Dissolve 100 mg in 2 mL of 1 N sodium hydroxide, add 1 drop of chloroform, and heat the mixture: an intense crimson color is produced. Then add a slight excess of hydrochloric acid: the color changes to pale yellow.
C: To 10 mL of a solution (1 in 100) add 1 drop of ferric chloride: a blue-violet color is produced, and it fades slowly.
Melting range: between 109 and 111 .
Loss on drying: Dry it over silica gel for 4 hours: it loses not more than 1.0% of its weight.
Residue on ignition: not more than 0.05%.
Phenol: Heat gently a solution (1 in 20): the odor of phenol is not perceptible.
Catechol: To 10 mL of a solution (1 in 20) previously mixed with 2 drops of 1 N acetic acid add 0.5 mL of lead acetate: no turbidity is produced.
Ordinary impurities: To pass the test.
Assay: Dissolve about 1.5 g of Resorcinol, accurately weighed, in water to make 500.0 mL. Transfer to an iodine flask 25.0 mL of the resulting solution, add 50.0 mL of 0.1 N bromine VS, dilute with 50 mL of water, add 5 mL of hydrochloric acid, and at once insert the stopper in the flask. Shake for 1 minute, allow to stand for 2 minutes, and add 10 mL of potassium iodide TS while slightly loosening the stopper. Shake thoroughly, allow to stand for 5 minutes, remove the stopper, and rinse it and the neck of the flask with 20 mL of water into the flask. Titrate the liberated iodine with 0.1 N sodium thiosulfate, adding starch as the endpoint is approached. Perform a blank determination. From the volume of 0.1 N sodium thiosulfate used, calculate the volume, in mL, of 0.1 N bromine consumed by the resorcinol. Each mL of 0.1 N bromine is equivalent to 1.835 mg of C6H6O2.

Fire Extinguishing Media: Use any means suitable for extinguishing surrounding fire. Water spray, alcohol-resistant foam, dry chemical, or carbon dioxide may be used to keep fire exposed containers cool.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. At high temperatures under fire conditions, it may produce toxic or irritating fumes. Fire-extinguishing work is done from the windward and the suitable fire-extinguishing method according to the surrounding situation is used. Uninvolved persons should evacuate to a safe place.

Personal precautions, protective equipment, and emergency procedures: Avoid breathing dust/fumes/gas/mist/vapors/spray. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Restrict unprotected personnel from the area. Prevent any contact with hot surfaces. Do not approach facing the wind. Do not touch the spilled material.
Environmental precautions: Do not let the product enter drains, soil, or water sources.
Methods and materials used for containment Cleanup procedures and Storage:
Small Spill: Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements.
Large Spill: Do not inhale vapors, mist, or gas. Avoid dust formation. Contain spilled material. Cover with an inert, non-combustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite). Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow to evacuate as per law.

Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. In case of insufficient ventilation, wear suitable respiratory equipment. Wash thoroughly after handling. Do not drink, eat, or smoke while handling. Avoid contact with skin, eyes, and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Prevent any contact with hot surfaces.
Conditions for safe storage, including any incompatibilities: Store in cool, dry, and ventilated area away from heat sources and protected from sunlight in tightly closed original container. Keep air contact to a minimum. Store protected from heat, sparks and ignition sources and incompatible materials. Avoid contact with skin and eyes. Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like strong oxidizing agents, iron, and iron salts. Further processing of solid materials may result in the formation of combustible dusts. The potential for combustible dust formation should be taken into consideration before additional processing.

Airborne Exposure Limits: TWA 10 ppm USA. ACGIH Threshold Limit Values (TLV)
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved): If the exposure limit is exceeded and engineering controls are not feasible, a half face piece particulate respirator (NIOSH type N95 or better filters) may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. A full-face piece particulate respirator may be worn. If oil particles (e.g. lubricants, cutting fluids, glycerin, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-face piece positive-pressure, air-supplied respirator.
Skin Protection: Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection: Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures: Maintain good housekeeping in work area. Dust deposits on floors and other surfaces may pick up moisture and cause the surfaces to become slippery and present safety hazards. Handle in accordance with good industrial hygiene and safety practice. Wash hands after handling.
