trichloroisocyanuric

Trichloroisocyanuric acid, often abbreviated as TCCA, is a chemical compound with the formula (C3Cl3N3O3). It is a white or off-white solid that is commonly supplied in granular, powder, or tablet form. TCCA is a chlorinated derivative of isocyanuric acid and is primarily used as a disinfectant, sanitizer, and biocide. Its main active component is the release of hypochlorous acid when dissolved in water, which is a powerful oxidizing agent effective against a wide range of bacteria, viruses, fungi, and algae.

The compound is widely employed in swimming pool and spa water treatment to maintain sanitation and prevent the growth of microorganisms. It is also utilized in industrial water treatment systems, such as cooling towers, to control slime and biofilm formation. In household settings, TCCA can be found in certain cleaning products and laundry bleaches, though its use is more prevalent in commercial and industrial applications due to its potency.

TCCA is considered a stable and efficient source of chlorine. It offers advantages over other chlorine-releasing compounds, such as liquid bleach or calcium hypochlorite, in terms of ease of handling, storage stability, and a slower, more controlled release of active chlorine. However, it is important to handle TCCA with care, as it can be irritating to skin, eyes, and respiratory passages. Proper ventilation and personal protective equipment are recommended when working with this chemical. It should also be stored away from incompatible materials, such as ammonia and organic compounds, to prevent hazardous reactions.
