Triazine is the six-membered heterocyclic ring containing three nitrogen which replaces carbon-hydrogen unit in the
benzene ring. Based on nitrogen position present in the ring system, it is categorized in three isomeric forms i.e.1, 2, 3-triazine
(vicinal triazine), 1, 2, 4-triazine (asymmetrical triazine or isotriazine) and 1, 3, 5-triazine (symmetrical or s-triazine or cyanidine). Triazines have weakly basic property. Its isomers have much weaker resonance energy than benzene structure, so nucleophilic substitution reactions are more preferred than electrophilic substitution reactions. Triazine isomers and their derivatives
are known to play important roles possessing various activities in medicinal and agricultural fields such as anti-cancer, antiviral,
fungicidal, insecticidal, bactericidal, herbicidal, antimalarial and antimicrobial agents.
