Trichloroisocyanuric Acid (TCCA)
CAS Number: 87-90-1
Trichloroisocyanuric acid (TCCA) is a stable, concentrated solid chlorine disinfectant with approximately 90% available chlorine content. It slowly releases hypochlorous acid in water, providing sustained chlorination and disinfection. TCCA is the most widely used chlorine source for swimming pool water treatment and is also used for disinfecting drinking water, food processing surfaces, and industrial cooling systems.
