Ammonium chloride

Ammonium chloride (CAS 12125-02-9), also known as E510 and NH4Cl, is an inorganic salt used across food, agricultural, and industrial manufacturing sectors. It functions primarily as a pH buffer, nitrogen source, and flame retardant depending on the application. In food production, E510 acts as a dough conditioner and yeast nutrient in bread and baked goods, improving fermentation consistency. Fertilizer blends and animal feed supplements rely on NH4Cl as a readily available nitrogen source.

This nitrogen source supports crop yield and livestock urinary health management. Textile and leather processors use it as a buffering agent in dyeing baths, where controlled pH directly affects color uptake and consistency across batches. In flame retardant formulations, it is incorporated into paper and textile treatments to reduce ignition risk in finished materials. Ammonium chloride is supplied as a white crystalline powder or fine granules for various uses.

Food-grade material is available to FCC and E510 specifications, while technical and agricultural grades serve industrial and fertilizer applications. These standards ensure the product meets specific purity requirements for safety. USP and BP grades are also recognized in the market for pharmaceutical and specialty uses. These high-quality standards allow for the chemical's use in sensitive medical and laboratory environments globally.
