Widely used as a disinfectant and biocide, this chemical is effective in water treatment, particularly for swimming pools and drinking water, due to its stable release of chlorine. It is commonly found in sanitizing solutions for food processing equipment, dairy and beverage industries, where strong germicidal action is required. Also used in household and industrial cleaners for surfaces, it controls bacteria, viruses, and fungi. Its high chlorine content and stability make it suitable for emergency water purification and in tablet or powder form for portable disinfection. Additionally, it is employed in laundry bleaches and hospital-grade disinfectants where reliable microbial control is essential.
