Trichloroisocyanuric Acid

Trichloroisocyanuric Acid, also known as TCCA, is a highly effective chlorinating agent and disinfectant widely used in water treatment, sanitation, and industrial processes. With the chemical identifier CAS NO 87-90-1, this compound is recognized for its stability and powerful oxidizing properties. It is commonly applied in swimming pools, spas, and drinking water purification to eliminate bacteria, algae, and other harmful microorganisms. The product's granular or tablet form allows for controlled release, ensuring efficient and long-lasting disinfection. Industries also utilize it in textile bleaching, paper manufacturing, and as a sanitizer in food processing facilities. Its high chlorine content and slow dissolution rate make it a preferred choice for maintaining hygiene standards in various applications.


Trichloroisocyanuric Acid is celebrated for its versatility and reliability in numerous sectors. Available in different concentrations, typically ranging from 90% to 98% purity, it meets diverse operational needs. The product's key parameters include a molecular weight of 232.41 g/mol, a melting point of approximately 225-230°C, and a chlorine content of up to 90%. It is soluble in water, releasing hypochlorous acid, which acts as a potent biocide. Safety measures are paramount when handling Trichloroisocyanuric Acid, as it requires storage in a cool, dry place away from organic materials to prevent reactions. Its effectiveness, combined with ease of use, has established it as a cornerstone in modern disinfection and sanitation practices worldwide.
