Isocyanuric acid

Isocyanuric acid (CAS 27026-93-3) is a triazine-based compound used industrially as a chlorine stabilizer and biocide carrier in water treatment and sanitization systems.

Where is Isocyanuric acid used?

• Water treatment: binds free chlorine, slowing photodegradation and extending disinfectant residuals
• Swimming pools and recreational water: stabilizes chlorine against UV degradation, cutting consumption and reapplication
• Sanitizers: precursor to trichloroisocyanuric acid (TCCA) and sodium dichloroisocyanurate (NaDCC), active disinfectants in tablet and granule formulations for pools, potable water and surface disinfection
• Industrial and institutional cleaning: buffering and stabilizing component in chlorine-releasing tablet systems
• Plastics: crosslinking agent and UV stabilizer precursor in polymer processing
• It serves as a precursor platform for chlorinated isocyanurate derivatives in cleaning and polymer applications.

Commercial specifications

• Purity typically 98–99%+
• Bulk supply in bags or supersacks
