Ammonium Chloride (CAS 12125-02-9) is a white, odorless crystalline salt of ammonium and chloride ions, commonly known as salammoniac, that serves as a flux in galvanizing, tinning and soldering, as an electrolyte in dry-cell batteries, and as a nitrogen source in fertilizers and pharmaceuticals. It provides both ammonium and chloride ions, making it valuable in metal treatment and buffer systems.
