Benzoguanamine is an organic compound with the chemical formula (CNH2)2(CC6H5)N3. It is related to melamine but with one amino group replaced by phenyl. Benzooguanamine is used in the manufacturing of melamine resins. Unlike melamine ((CNH2)3N3), benzoguanamine is not a crosslinker. The "benzo" prefix is historical, the compound contains phenyl, not a benzo group. A related compound is acetoguanamine.[1]

The compound is prepared by condensation of cyanoguanidine with benzonitrile.[2]

(H2N)2C=NCN + PhCN → (CNH2)2(CPh)N3

Safety

LD50 (oral, rats) is 1470 mg/kg.
