Sodium dichloroisocyanurate dihydrate (NaDCC) is a calibration substance for the photometric determination of active chlorine. It is used to study the effects of chlorine on bacteria, viruses, other microorganisms, and the environment. It is also used as a disinfectant, sanitizer, and bleaching agent in a variety of industries. When NaDCC is added to water, it breaks down into hypochlorous acid and urea. The hypochlorous acid then acts as a disinfectant, killing bacteria, viruses, and other microorganisms. The urea acts as a stabilizer, preventing the hypochlorous acid from breaking down too quickly.
