Ammonium chloride is used for the lysis of human red blood cells. It is used in protein isolation techniques and in the study of basic calcium phosphate crystals in fibroblasts. It inhibits intracellular dissolution of basic calcium phosphate (BCP) crystals by alkalinizing phagolysosomes. It is used as a flavoring agent in some types of liquorices. It is also used as electrolyte in zinc-carbon batteries.
