Potassium Bromide USP Grade Specifications
KBr -- 119.0
Potassium Bromide contains not less than 98.0 percent and not more than 100.5 percent of KBr, calculated on the dried basis. It contains no added substances.
Appearance of solution: clear and colorless.
Test solution: Dissolve 10.0 g in carbon dioxide-free water, and dilute with the same solvent to 100 mL.
Identification:
A: A solution containing 4.5 mg of potassium bromide responds to the test for Bromide.
B: Responds to the test for Potassium.
Acidity or alkalinity: To 10 mL of the solution prepared for the test for Appearance of solution, add 0.1 mL of bromothymol blue TS: not more than 0.5 mL of 0.01 N hydrochloric acid or 0.01 N sodium hydroxide is required to change the color of this solution.
Loss on drying: Dry it at 100 to 105 for 3 hours: it loses not more than 1.0% of its weight.
Bromates:
Starch–mercuric iodide solution: Triturate 1.0 g of soluble starch with 5 mL of water and pour the mixture into 100 mL of boiling water, containing 10 mg of mercuric iodide.
Procedure: To 10 mL of the solution prepared for the test for Appearance of solution add 1 mL of Starch–mercuric iodide solution, 0.1 mL of a 100 g per L solution of potassium iodide, and 0.25 mL of 0.5 M sulfuric acid. Allow to stand protected from light for 5 minutes: no blue or violet color develops.

The Uses of Potassium Bromide:
Potassium bromide is a halide salt most commonly used as an add-on anticonvulsant drug to phenobarbital when the latter is ineffective or not as effective as desired. It also may permit you to decrease the dose level of the phenobarbital. Potassium bromide may also be used initially as the sole anticonvulsant drug. Potassium Bromide is used to manufacture photographic papers and plates. Used as a laboratory agent. Used as a heat stabiliser for nylon. Used as a Sedative. Potassium bromide is an antiepileptic medication used in dogs to treat seizures. Potassium bromide is used as a hypnotic and sedative in cattle, horses, sheep and pigs.
