Dichloroisocyanuric acid, also known as dichlor or dichloro-s-triazinetrione and which 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 commercial bacteriocides, algicides, and cleaning agents. It is an oxidizer that reacts with water to form hypochlorous acid, a compound related to the active ingredient in bleach.

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

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

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.
