### Product Introduction

**Sodium Dichloroisocyanurate** (SDIC or NaDCC) is a sodium salt derived from chlorinated hydroxy triazine, commonly used as a chlorine source in the form of hypochlorous acid for disinfecting water. SDIC is known for its strong oxidizing properties and effective bactericidal action against a wide range of pathogenic microorganisms, including viruses, bacterial spores, and fungi. It is a widely recognized and highly efficient disinfectant.

As a reliable and stable chlorine source, SDIC is used in swimming pool disinfection and food sterilization. Additionally, it is effective for purifying drinking water during emergencies, owing to its steady chlorine release.
