Sodium Dichloroisocyanurate (C3N3O3Cl2)
Sodium Dichloroisocyanurate (NaDCC) is a white crystalline powder used primarily as a disinfectant, sanitizer, and biocide. It is a stable, slow-releasing chlorine compound effective against bacteria, viruses, and fungi. Widely applied in water treatment, swimming pool sanitation, food processing, and healthcare, it provides long-lasting antimicrobial activity. Its high chlorine content and ease of handling make it an essential chemical for hygiene and sterilization applications.
