Description

Cyanuric chloride (CAS 108-77-0 ), also known as sym-trichlorotriazine, is a reactive triazine intermediate used across chemical synthesis and industrial manufacturing. Its three replaceable chlorine atoms make it a building block for producing dyes and agrochemicals. This versatile compound is essential for manufacturing UV stabilizers and flame retardants at a commercial scale. In textile processing, it acts as a coupling agent for reactive dyes, bonding colorants permanently to cellulose fibers in cotton dyeing operations. Coatings and polymer formulators use it to synthesize UV absorbers and light stabilizers that protect resins, films, and surface coatings from photodegradation. These applications ensure long-term durability for materials exposed to sunlight. Water treatment chemical producers rely on it as a precursor to chlorinated isocyanurates used for disinfection and algae control. It plays a critical role in maintaining safety standards for industrial and municipal water systems. In flame retardant production, it serves as a core scaffold for nitrogen-based FR additives incorporated into plastics and elastomers. This functionality is vital for meeting fire safety regulations in the construction and automotive sectors. Cyanuric chloride is supplied as a white crystalline powder or flakes. Technical grade is the standard commercial form, with purity typically specified at 98% or higher for industrial synthesis applications. It is packaged in moisture-controlled containers given its reactivity with water during storage and transport. Proper handling ensures the material maintains its chemical integrity for high-precision manufacturing processes. Contact us for supply of Cyanuric chloride Request Quote
