title: Conversion of biguanides into substituted s-triazines assayable by GC or mass fragmentography.
abstract: Substituted s-triazines were prepared by the treatment of biguanides with various organic acid anhydrides. This reaction permits the ready conversion of the hypoglycemic drugs phenformin, buformin, and metformin and of other analogous biguanides into compounds suitable for GC and mass fragmentographic determination with a high degree of sensitivity. Mass spectral data and Kováts retention indexes are presented for all s-triazines prepared for this study.
