Trichloroisocyanuric acid - Wikipedia
Trichloroisocyanuric acid - Wikipedia

Trichloroisocyanuric acid, is an organic compound with the formula (C 3 Cl 3 N 3 O 3).It is used as an industrial disinfectant, bleaching agent and a reagent in organic synthesis. This white crystalline powder, which has a strong "chlorine odour," is sometimes sold in tablet or granule form for domestic and industrial use.Salts of ,trichloroisocyanuric acid, are known as trichloroisocyanurates
