Dichloroisocyanuric acid, also known as dichlor or dichloro-s-triazinetrione and is marketed under many names (e.g. troclosene), is a chemical compound with the formula (C(O)NCl)2(C(O)NH). This colourless solid is the active ingredient in many commercial bacteriocides, algicides, and cleaning agents. It is an oxidizer that reacts with water to form hypochlorous acid, the sodium salt of which is the active ingredient in bleach.

The sodium salt of dichloroisocyanuric acid, sodium dichloroisocyanurate, is the active ingredient in the powderized cleanser Comet and is also used as a pool disinfectant.

Synthesis

It is manufactured by chlorination of cyanuric acid:[1]

(C(O)NH)3 + 2 Cl2 → (C(O)NCl)2(C(O)NH) + 2 HCl
