Abstract The stability of trimelamol N 2, N 4, N 6-trimethylol-N 2, N 4, N 6- (trimethylmelamine) a synthetic carbinolamine-containing antitumor drug, has been studied. Two major degradation pathways have been characterized and a unified mechanism proposed to rationalize the chemistry involved. One degradation pathway involves the consecutive loss of hydroxymethylene units by elimination of formaldehyde until the ...
