Ammonium chloride CAS#：12125-02-9
Products Description — Ammonium Chloride (CAS No. 12125-02-9)
Ammonium chloride (referred to as "chloramine", also known as halogen sand, chemical formula: NH₄Cl) is colorless cubic crystal or white crystalline powder. It tastes salty and slightly bitter and belongs to acid salt. Its relative density is 1.527. It is soluble in water, ethanol and liquid ammonia but insoluble in acetone and ether. The aqueous solution is weakly acidic, and its acidity is enhanced while heating. When heated to 100 °C, it begins to significantly volatilize, and when heated to 337.8 °C, it will dissociate into ammonia and hydrogen chloride, which, on cold exposure, will re-combine to produce small particles of ammonium chloride and white smoke that is not easy to sink and is very difficult to dissolve in water. When heated to 350 °C, it will sublimate, and when 520 °C, it will boil. Its moisture absorption is small, and in wet rainy weather it can absorb moisture to cake. It is corrosive to ferrous metals and other metals, which, in particular, has greater corrosion of copper but no corrosion of pig iron. Ammonium chloride can be obtained from the neutralization reaction of ammonia and hydrogen chloride or ammonia and hydrochloric acid (reaction equation: NH₃ + HCl → NH₄Cl). When heated, it will decompose into hydrogen chloride and ammonia (equation: NH₄Cl → NH₃ + HCl), and the reaction is only to the right if the container is open system.

Product Application of Ammonium Chloride (CAS No. 12125-02-9)
1. Major Applications
Ammonium chloride is mainly used for dry batteries, storage batteries, ammonium salts, tanning, plating, medicine, photography, electrodes, adhesives, etc. It is also an available nitrogen chemical fertilizer whose nitrogen content is 24% to 25%. It is a physiological acidic fertilizer and suitable for wheat, rice, corn, rapeseed and other crops. It has the effects of enhancing fiber toughness and tension and improving quality, especially for cotton and linen crops. However, due to the nature of ammonium chloride, if the application is not right, it will bring some adverse effects to soil and crops.
2. Additional Application Scenarios
Beyond the above, ammonium chloride is widely applied as a soldering flux and in hot-dip galvanizing and metal cleaning baths, as well as in ice-making and refrigerating brine systems. It is also used as a dyeing assistant in textile finishing processes, as a reagent and buffer component in analytical laboratories, and as a permitted processing aid in certain pharmaceutical and food applications.
3. Technical Conditions & Standards
Implemented in accordance with the People's Republic of China national standard GB-2946-82: the product appears as white crystal, with an ammonium chloride content (dry basis) of ≥ 99.3%, a moisture content of ≤ 1.0%, a sodium chloride content (dry basis) of ≤ 0.2%, an iron content of ≤ 0.001%, a heavy metal content (in terms of Pb) of ≤ 0.0005%, a water insoluble content of ≤ 0.02%, a sulfate content (in terms of SO₄²⁻) of ≤ 0.02%, and a pH of 4.2–5.8.
