Trichloroisocyanuric acid is an organic compound with the formula (C3Cl3N3O3). It is used as an industrial disinfectant, bleaching agent and a reagent in organic synthesis.[1][2] This white crystalline powder, which has a strong "chlorine odour," is sometimes sold in tablet or granule form for domestic and industrial use.

Applications[edit]

The compound is a disinfectant, algicide and bactericide mainly for swimming pools and dyestuffs, and is also used as a bleaching agent in the textile industries. It is widely used in civil sanitation, pools and spas, preventing and curing diseases in husbandry and fisheries, fruits and vegetables preservation, wastewater treatment, algicide for recycling water of industry and air conditioning, anti shrink treatment for woolen, treating seeds, bleaching fabrics, and organic synthesis.

Trichloroisocyanuric acid in swimming pools is easier to handle than chlorine. It dissolves slowly in water, but as it reacts, cyanuric acid concentration in the pool will build-up. At high cyanuric acid concentrations, normal chlorine levels can be rendered ineffective, requiring either dilution by draining and refilling the pool or by adding abnormally high doses of chlorine to overcome this effect.
