Product Usage

Ammonium Chloride is a versatile inorganic salt with critical applications in agriculture, industry, and medicine. In agriculture, it serves as an efficient nitrogen fertilizer, particularly suitable for crops like rice and wheat, where it promotes protein synthesis and enhances lodging resistance. In the industrial sector, it acts as an electrolyte in dry cell batteries and functions as a flux in metal welding and galvanizing processes, clearing oxides from metal surfaces to ensure high-quality bonding. Additionally, it is widely utilized in textile dyeing, leather tanning, and as a food additive (e.g., as a yeast nutrient in bread making). In pharmacy, it is commonly used as an expectorant to help thin mucus for easier expulsion.
