Ammonium Chloride

Drug Details

Ammonium chloride is a white, crystalline compound with the chemical formula NH₄Cl, known for its high solubility in water and slightly acidic nature. Historically referred to as sal ammoniac, it has been utilized since ancient times. Today, ammonium chloride serves multiple purposes across various industries. In agriculture, it acts as a nitrogen-rich fertilizer, particularly benefiting rice and wheat crops. The pharmaceutical industry employs it as an expectorant in cough medicines to help clear mucus from the respiratory tract. In metalworking, it functions as a flux to clean metal surfaces before processes like tinning, galvanizing, or soldering. Additionally, ammonium chloride is used in dry cell batteries as an electrolyte and in the food industry as a flavoring agent in certain types of licorice. While generally safe when handled properly, exposure to its fumes can irritate the respiratory system, eyes, and skin, necessitating appropriate safety measures during its use.
