Description

Dichloroisocyanurate (CAS 2782-57-2 ), commonly supplied as its sodium or potassium salt, is a chlorine-releasing compound used across water treatment, sanitation, and cleaning applications. It delivers controlled, stabilized active chlorine that disinfects, bleaches, and controls microbial growth across a broad range of industrial and consumer end uses. In water treatment, it serves as the active disinfectant in swimming pool and potable water systems, where its slow chlorine release maintains residual sanitizer levels more effectively. Industrial and institutional cleaning formulators incorporate it into dishwashing powders, surface sanitizers, and hard-surface disinfectants targeting bacteria, fungi, and algae. Laundry and textile bleaching products rely on it to deliver oxidative whitening without the handling risks associated with liquid hypochlorite in various industrial settings. In personal care, it is used at low concentrations in denture-cleaning tablets and wound-care formulations requiring controlled antimicrobial action for safety and efficacy. Dichloroisocyanurate is commercially available as a dry, free-flowing powder or in tablet and granule form, most commonly as the sodium salt (NaDCC) or potassium salt. Standard grades include technical, food-grade, and potable water treatment specifications, with active chlorine content typically confirmed against recognized standards like FCC .
