Cyanuric acid, also known as isocyanuric acid, is a non-toxic, odorless white crystal with a specific gravity of 1.768 g/cm3 for the dihydrate form and 2.5 g/cm3 for the anhydrous form. It carries two water molecules when crystallizing from water and forms octahedral, anhydrous crystals in dry air. Cyanuric acid has no obvious melting point and generally melts and decomposes above 330C. Cyanuric acid is an important organic basic raw material with hundreds of downstream products. Its primary uses include disinfectants (sodium dichloroisocyanurate and trichloroisocyanuric acid), and as a monomer in the production of heat-resistant, flame-retardant synthetic materials like polyester imide insulating varnish. The use of cyanuric acid-based disinfectants has been growing rapidly in recent years. The demand for heat-resistant polyester insulating varnish modified with cyanuric acid has also increased, driven by the need for motors with large power and small size.
