Infobox references

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).

Synthesis

Dichloroisocyanuric acid is manufactured by chlorination of cyanuric acid:^[1]

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

It is a colourless solid.

Mechanism of action

Dichloroisocyanuric acid is an oxidizer, reacting with water to form hypochlorous acid.

The sodium salt of dichloroisocyanuric acid, sodium dichloroisocyanurate, is the active ingredient in bleach. It is the active ingredient in many commercial disinfectant bacteriocides, algicides, and cleaning agents., for example the powderized cleanser Comet.
