Ammonium Chloride USP Grade Specifications
NH4Cl -- 53.49

Assay: Ammonium Chloride contains not less than 99.5 percent and not more than 100.5 percent of NH4Cl, calculated on the dried basis.
Identification: A solution (1 in 10) responds to the tests for Ammonium and for Chloride
pH: between 4.6 and 6.0, in a solution (1 in 20).
Loss on drying: Dry it over silica gel for 4 hours: it loses not more than 0.5% of its weight.
Residue on ignition: Add 1 mL of sulfuric acid to about 2 g, accurately weighed, and heat the mixture gently until volatilization is complete: the residue is white, and when ignited, not more than 0.1% of nonvolatile substance remains.
Limit of thiocyanate: Acidify 10 mL of a solution (1 in 10) with hydrochloric acid, and add a few drops of ferric chloride TS: no orange-red color is produced.
Heavy metals: 0.001%.


Ammonium Chloride FCC Food Grade Specifications

NH4Cl Formula weight 53.49

DESCRIPTION
Ammonium Chloride occurs as colorless crystals or as a white, fine or coarse, crystalline powder. It is somewhat hygroscopic. One gram dissolves in 2.6 mL of water at 25°, in 1.4 mL of boiling water, in about 100 mL of alcohol, and in about 8 mL of glycerin. The pH of a 1:20 solution is between 4.5 and 6.0.

REQUIREMENTS
Identification: A 1:10 aqueous solution gives positive tests for Ammonium and for Chloride.
Assay: Not less than 99.0% of NH4Cl after drying.
Lead: Not more than 4 mg/kg.
Loss on Drying: Not more than 0.5%.
