Methanediamine Dihydrochloride, >=98% (4 Times Purification)

Cat No:BMSPEM-0082

Description

Methanediamine dihydrochloride, also known as methylenediamine dihydrochloride, is a doubly protonated geminal diamine salt supplied at >=98% purity after four purification cycles. Beyond its role as a perovskite precursor, the salt acts as a reactant in condensation polymerizations such as the synthesis of polymethylene biguanide from sodium dicyanamide in butanol, in amidation reactions, and as a hydrogen source in catalytic hydrogenation. Cold-chain storage at 2-8°C under argon preserves reagent quality during transport and handling.
