Chemical compound
Heptazine, or tri-s-triazine or cyamelurine, is a chemical compound with formula C 6N 7H 3, that consist of a planar triangular core group or three fused triazine rings, with three hydrogen atoms at the corners. It is a yellow, weakly fluorescent solid with melting point over 300 °C. It is soluble in organic solvents such as acetonitrile, but is decomposed by water in the presence of light.[1][2]
The name "heptazine" is also used for derivative compounds, which have the three hydrogens substituted by other functional groups. Heptazine oligomers and polymers were discovered in the 19th century but their study has long been hampered by their general insolubility. They are used as flame retardants. Heptazine derivatives have been the object of interest recently for potential applications in electronics materials, explosives, and more. The synthesis of heptazine proper was reported only in 1982.[3]
