Specifications
We make Ammonium Chloride Crystals, Bricks, Pellets and Tablets in
bulk. USP BP IP
Ammonium Chloride USP
NH4Cl *3.*9
Ammonium Chloride
Assay- Ammonium Chloride contains not less than *9.5 percent and
not more than **0.5 percent of NH4Cl, calculated on the dried
basis.
Packaging and storage- Preserve in tight containers.
Identification- A solution (1 in *0) responds to the tests for
Ammonium and for Chloride
pH between 4.6 and 6.0, in a solution (1 in *0).
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 *0 mL of a solution (1 in *0)
with hydrochloric acid, and add a few drops of ferric chloride
TS: no orange-red color is produced.
Heavy metals : 0.**1%.
