Zinc Chloride USP Specifications
Zinc Chloride ZnCl2 136.30
Assay— Zinc Chloride contains not less than 97.0 percent and not more than 100.5 percent of ZnCl2.
Packaging and storage— Preserve in tight containers.
Identification— A solution of it responds to the tests for Zinc and for Chloride.
Limit of oxychloride— Dissolve 1.0 g in 20 mL of water, add 20 mL of alcohol, and mix. To 10 mL of the mixture add 0.30 mL of 1.0 N hydrochloric acid: the solution becomes perfectly clear.
Sulfate— Dissolve 1.0 g in 30 mL of water: 20 mL of this solution shows no more sulfate than corresponds to 0.20 mL of 0.020 N sulfuric acid (0.03%).
Limit of ammonium salts— To 5 mL of a solution (1 in 10) add 1 N sodium hydroxide until the
precipitate first formed is re-dissolved, and then warm the solution: no odor of ammonia is perceptible.
Lead— Dissolve 0.50 g in 5 mL of water, and transfer the solution to a color-comparison tube (A). Add 15 mL of Potassium Cyanide Solution (1 in 10), mix, and allow the mixture to become clear. In a similar, matched color-comparison tube (B) place 5 mL of water, and add 2.50 mL of Standard Lead Solution (see Heavy Metals 231 ) and 15 mL of Potassium Cyanide Solution (1 in 10). Add to the solution in each tube 0.1 mL of sodium sulfide TS. Mix the contents of each tube, and allow to stand for 5 minutes: viewed downward over a white surface, the solution in tube A is not darker than that in tube B (indicating not more than 0.005% of lead).
Alkalies and alkaline earths— Dissolve 2.0 g in about 150 mL of water contained in a 200-mL volumetric flask. Add sufficient ammonium sulfide TS to precipitate the zinc completely, dilute with water to volume, and mix. Filter through a dry filter, and reject the first portion of the filtrate. To 100 mL of the subsequent filtrate add 5 drops of sulfuric acid, evaporate to dryness, and ignite: the weight of the residue does not exceed 10 mg (1.0%).
Organic volatile impurities: meets the requirements.
Zinc Chloride as per BP Specifications
Zinc Chloride ZnCl2
DEFINITION
Content
95.0 per cent to 100.5 per cent.
CHARACTERS
Appearance
White or almost white, crystalline powder or cast in white or almost white sticks, deliquescent.
Solubility
Very soluble in water, freely soluble in ethanol (96 per cent) and in glycerol.
IDENTIFICATION
A. Dissolve 0.5 g in dilute nitric acid R and dilute to 10 ml with the same acid. The solution gives reaction of chlorides.
B 5 ml of solution S gives the reaction of zinc.
TESTS
Solution S
To 2.0 g add 38 ml of carbon dioxide-free water R prepared from distilled water and add dilute hydrochloric acid drop wise until dissolution is complete. Dilute to 40 ml with carbon dioxide-free water prepared from distilled water.
pH
4.6 to 5.5.
Dissolve 1.0 g in 9 ml of carbon dioxide-free water, ignoring any slight turbidity.
Oxychloride
Dissolve 1.5 g in 1.5 ml of carbon dioxide-free water R. The solution is not more opalescent than reference suspension. Add 7.5 ml of ethanol (96 per cent). The solution may become cloudy within 10 min. Any cloudiness disappears on the addition of 0.2 ml of dilute hydrochloric acid.
Sulphates
Maximum 200 ppm.
Aluminium, calcium, heavy metals, iron, magnesium
To 8 ml of solution S add 2 ml of concentrated ammonia R and shake. The solution is clear and colourless. Add 1 ml of disodium hydrogen phosphate solution. The solution remains clear for at least 5 min. Add 0.2 ml of sodium sulphide solution. A white precipitate is formed and the supernatant liquid remains colourless.
Ammonium
Maximum 400 ppm.
Zinc Chloride Injection as per USP Specifications
Zinc Chloride Injection is a sterile solution of Zinc Chloride in Water for Injection. It contains not less than 90.0 percent and not more than 110.0 percent of the labeled amount of zinc (Zn).
Packaging and storage— Preserve Zinc Chloride in single-dose or multiple-dose containers, preferably of Type I or Type II glass.
Labeling— Label the Injection to indicate that it is to be diluted with Water for Injection or other suitable fluid to appropriate strength prior to administration.
Identification— The Assay preparation prepared as directed in the Assay exhibits an absorption maximum at about 213.8 nm, when determined as directed in the Assay.
Bacterial endotoxins 85 — It contains not more than 25.0 USP Endotoxin Units per mg of zinc.
pH: between 1.5 and 2.5.
Particulate matter: meets the requirements for small-volume injections.
Other requirements— It meets the requirements under Injections 1
