It is a six-membered heterocyclic aromatic ring, one of several isomeric triazines. S-triazine and its derivatives are useful in a variety of applications. ==Preparation== Symmetrical 1,3,5-triazines are prepared by trimerization of certain nitriles such as cyanogen chloride or cyanimide. Benzoguanamine (with one phenyl and 2 amino substituents) is synthesised from benzonitrile and dicyandiamide.〔''Benzoguanamine'' J. K. Simons and M. R. Saxton Organic Syntheses Coll. Vol. 4, p.78; Vol. 33, p.13 (Article )〕 In the Pinner triazine synthesis (named after Adolf Pinner )〔A. Pinner, Ber. 23, 2919 (1890)〕 the reactants are an alkyl or aryl amidine and phosgene 〔''Name reactions and reagents in organic synthesis'', Bradford P. Mundy, Michael G. Ellerd, Frank G.

Chem. Soc., 1956, 78 (11), pp 2447–2451 〕 Insertion of N-H moiety into hydrazide by a copper carbenoid, followed by treatment with ammonium chloride also gives the triazine core.〔Shi, B.; Lewis, W.; Campbell, I.
