Aluminum Phosphate Gel
Aluminum Phosphate Gel USP Grade Specifications:
Phosphoric acid, aluminum salt (1:1).
Aluminum phosphate (1:1) CAS 7784-30-7
UNII: F92V3S521O
Aluminum Phosphate Gel is a water suspension containing not less than 4.0 percent and not more than 5.0 percent (w/w) of aluminum phosphate (AlPO4). It may contain sodium benzoate, benzoic acid, or other suitable agent in an amount not exceeding 0.5 percent, as a preservative.
Identification:
A: A solution of it in hydrochloric acid meets the requirements of the tests for Aluminum.
B: A solution of it in 2 N nitric acid meets the requirements of the tests for Phosphate.
pH: between 6.0 and 7.2.
Soluble phosphate: To pass the test. The soluble phosphate, calculated as PO4 does not exceed 0.30%.
Sulfate: --- not more than 0.05% is found.
Arsenic: Prepare the Test Preparation by dissolving 5.0 g of Gel in the smallest necessary volume of 3 N hydrochloric acid. The limit is 0.6 ppm.
Chloride: --- Not more than 0.16% of chloride is found.
Aluminium Phosphate Gel BP Ph Eur Grade Specifications:
Action and use: Antacid; vaccine adjuvant.
DEFINITION
