Product Description
Ammonium Chloride is a highly soluble, white, odorless crystalline salt with a mildly acidic nature in aqueous solutions. It is hygroscopic, readily absorbing moisture from the air, and forms clear solutions in water. Ammonium chloride is stable under normal storage but can react with strong bases and acids. Its solutions are mildly corrosive and can acidify their environment, making it useful for a wide range of industrial and scientific applications.

Application Sectors and Industries of Ammonium Chloride
Agriculture and Fertilizers
Ammonium chloride is a valuable nitrogen source in fertilizers, especially for rice and wheat. It promotes rapid plant growth and is favored in chloride-tolerant crops where it improves yield and soil fertility.
Metal Processing and Metallurgy
Widely used as a flux in galvanizing, tinning, and soldering, ammonium chloride removes metal oxides and ensures strong adhesion of coatings. It is also used in the preparation of zinc and tin surfaces for enhanced corrosion resistance.
Pharmaceuticals and Medicine
Ammonium chloride acts as an expectorant in cough syrups, helping to loosen mucus in the respiratory tract. It is also used to acidify urine and manage certain metabolic disorders and urinary tract infections.
Food and Beverage Industry
Food-grade ammonium chloride is used as a leavening agent in baking powders, a flavoring in licorice, and a pH regulator in processed foods and beverages. Its use is subject to strict regulatory standards.
Battery Manufacturing
Essential as an electrolyte in zinc-carbon dry cell batteries, it improves conductivity and enhances battery performance and shelf life.
Textile and Dyeing
Ammonium chloride serves as a dye-fixing agent in textile printing and dyeing, improving color fastness and uniformity on fabrics.
Laboratory and Chemical Synthesis
Used as a reagent and buffer in analytical chemistry, ammonium chloride is vital for experimental studies, buffer solutions, and chemical syntheses.
Water Treatment
Applied in chloramination processes for water purification, ammonium chloride helps control microbial growth and maintain water quality in municipal systems.
Environmental and Smoke Generation
Used in smoke-producing compounds for military, special effects, and fire training applications, ammonium chloride creates dense, non-toxic smoke.
Mining and Explosives
Acts as a component in explosives and blasting agents, and is used for pH control and mineral processing in mining operations.
