Description

General description

Methylenediamine dihydrochloride, also known as Diaminomethane dihydrochloride is an organic compound that is often utilized as a reagent and slow ammonia-releasing agent during the synthesis of primary amides of peptides and amino acids from active esters.

Application

Methylenediamine dihydrochloride can be used as a reactant to synthesize:

• Poly(methylene biguanides) via polycondensation reaction with sodium dicyanamide in the presence of 1-butanol.
• Didodecanoylamides by reacting with (2S)-2-methyldodecanoyl chloride via acylation in the presence of sodium bicarbonate.

It can also be used as a hydrogen source in catalytic hydrogenation reactions.
