AMMONIUM CHLORIDE ACS REAGENT >=99.5% (C005B-011568)

General description

Crystals of ammonium chloride (NH₄Cl) belong to the cubic crystal system. It can be synthesized by reacting HCl with aqueous ammonia solutions. NH₄Cl is formed as a by-product during soda manufactured by Solvay process.

Application

Ammonium chloride (NH₄Cl) has been used as one of the components of red blood cell (RBC) lysis buffer for use in various studies. It may be used as a catalyst in the preparation 3,4-dihydropyrimidin-2-(1H)-ones.
Inorganic ammonium ions (NH₄⁺) effectively catalyze the aldol condensation of carbonyl compounds. It serves as a source of nitrogen during the preparation of trimethylamine hydrochloride (TMA·HCl).
