Dihydralazine mesylate

Dihydralazine mesylate is a methanesulfonate salt derived from dihydralazine, characterized by a 1,2-diamino-4,5-dihydro-1H-imidazole-2-thione core substituted with two hydrazine moieties. The mesylate counterion (CH3SO3^-) forms a stable ionic bond with a protonated amine, enhancing aqueous solubility. This impurity arises from synthetic bypaths during hydralazine production, where methanesulfonic acid mediates salt formation. It functions as an HPLC reference standard for quantifying process-related impurities in parent drug formulations.
