Cyanuric acid

Cyanuric acid (CAS 108-80-5) is a triazine-based compound used industrially as a stabilizer, biocide precursor, and flame retardant intermediate.

Where is Cyanuric acid used?

• Water treatment: extends the effective life of chlorine-based disinfectants by reducing UV degradation
• Swimming pool and recreational water treatment: stabilizes free chlorine against photodegradation
• Polymer and textile applications: building block for flame retardant systems and crosslinking agents
• Textile and leather processing: component in crosslinking systems that improve dye fixation and substrate durability
• Paper treatment: wet-strength resin formulations
• Bleaching processes: chlorine stabilizer
• Polymer formulators use it as a precursor to melamine cyanurate, a halogen-free flame retardant additive incorporated into nylon and engineering plastics.

Commercial specifications

• Purity typically 98% or higher
• Packaging from small bags to bulk quantities
