Eleven symmetrical triazine derivatives containing 1,2,4-triazole and 3-amino-1,2,4-triazole substituents have been prepared. The derivatives with 1,2,4-triazole substituents were synthesized by reacting N,N '-diformylhydrazine with certain amine derivatives of cyanuric chloride. The derivatives with 3-amino-1,2,4-triazole substituents were synthesized by reacting 3-amino-1,2,4-triazole with cyanuric chloride per se. Five of the derivatives were screened for anticarcinogenic and herbicidal properties. No anticarcinogenic or herbicidal effects were detected. Mouse behavior studies showed that three of the five were weak central nervous system depressants.
