Thymolphthalein Analytical Reagent Grade Specifications:
5',5"-Diisopropyl-2',2"-dimethylphenolphthalein
3,3-Bis[4-hydroxy-2-methyl-5-(1-methylethyl)phenyl]-1(3H)-isobenzofuranone
C28H30O4 -- Formula Weight 430.54
CAS Number 125-20-2

REQUIREMENTS
Clarity of solution: Dissolve 0.1 g in 100 mL of alcohol. No more than a faint trace of turbidity or insoluble matter should remain. Use the solution for the test for visual transition interval.
Visual transition interval: Dissolve 1 g of potassium chloride in 100 mL of water. Adjust the pH of the solution to 8.80 (using a pH meter) with 0.01 N sodium hydroxide. Add 0.5-1.0 mL of the 0.1% solution reserved from the test for clarity of solution. The solution should be colorless. Titrate the solution with 0.01 N sodium hydroxide to pH 9.4 (using the pH meter). The solution should have a pale grayish-blue color. Continue the titration to pH 9.9. The solution should have a blue color. Not more than 2.0 mL of 0.01 N sodium hydroxide should be consumed in the titration. Each additional 0.05 mL of 0.01 N sodium hydroxide should increase the amount of blue color until at pH 10.5 the color should be an intense blue.

GHS, Globally Harmonized System Classification in accordance with 29 CFR 1910
Hazard Class and Category Code(s), Regulation (EC) No 1272/2008 (CLP)

Not a hazardous substance or mixture according to Regulation (EC) No. 1272/2008.
This substance is not classified as dangerous according to Directive 67/548/EEC.

Hazards not otherwise classified (HNOC):
May causes mild skin irritation.
May causes mild eye irritation, if exposed in large quantity.

Precautionary statements:
P261: Avoid breathing dust/fume/gas/mist/vapors/spray.
P262: Do not get in eyes, on skin, or on clothing.
P281: Use personal protective equipment as required.
P302+P352: IF ON SKIN: Wash with plenty of soap and water.
P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing.
P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
P337+313: If eye irritation persists get medical advice/attention.

Product Name & Other Names: Thymolphthalein.
CAS Number: 125-20-2
EINECS EC Number: 204-729-7

Emergency and First Aid Procedures:
Eyes - Flush with water for at least 15 minutes, raising and lowering eyelids occasionally. Get medical attention if irritation persists.
Skin - Thoroughly wash exposed area for at least 15 minutes. Remove contaminated clothing. Launder contaminated clothing before reuse. Get medical attention if irritation persists.
Ingestion - If it is swallowed, if conscious, give plenty of water. Immediately call a physician. Never give anything by mouth to an unconscious person.
Inhalation - Remove to fresh air. Give oxygen if breathing is difficult; give artificial respiration if breathing has stopped. Get medical attention.

Extinguisher Media: Use media suitable to extinguish surrounding fire. Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
Flammable Limits in Air % by Volume: N/A
Special hazards arising from the substance or mixture: Carbon oxides and fumes.
Extinguishing Media Not recommended: Avoid using solid water jet as it may scatter the fire.
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 a 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: Contain spilled material. Cover with an inert, non-combustible absorbent material, (e.g., sand, earth, diatomaceous earth, vermiculite). Vacuum or sweep up and remove to an approved disposal container.

Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. 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. 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. Do not leave the material container open. 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 oxidizing agents. Storage: Room temperature.

Exposure Limits: No additional information available.
Respiratory Protection (Specify Type): None needed under normal conditions of use with adequate ventilation. NIOSH approved equipment should be worn if exposure is high.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator may be worn. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator.
Skin Protection: Wear protective gloves and clean body-covering clothing.
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.
