General description

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. Ammonium chloride is formed as a by-product during soda manufacturing by Solvay process. It can be synthesized by reacting HCl with aqueous ammonia solutions. Crystals of ammonium chloride (NH₄Cl) belong to the cubic crystal system.
