Cyanuric chloride
What is Cyanuric chloride?
Cyanuric chloride (CAS 108-77-0), also known as sym-trichlorotriazine, is a reactive triazine intermediate used in chemical synthesis and industrial manufacturing.
Where is Cyanuric chloride used?
- Dyes and agrochemicals: building block via three replaceable chlorine atoms
- UV stabilizers and flame retardants: commercial-scale manufacturing
- Textile processing: coupling agent for reactive dyes bonding to cellulose fibers in cotton dyeing
- Coatings and polymers: synthesis of UV absorbers and light stabilizers protecting resins, films and surface coatings from photodegradation
- Water treatment: precursor to chlorinated isocyanurates for disinfection and algae control
- Flame retardant production: core scaffold for nitrogen-based FR additives in plastics and elastomers
- It is packaged in moisture-controlled containers because it reacts with water during storage and transport.
Good to know: Technical grade is the standard commercial form, typically specified at 98% purity or higher for industrial synthesis. Reacts with water, so moisture-controlled handling is needed.
Commercial specifications
- Purity typically 98% or higher
- Moisture-controlled containers
