Allgemeine Beschreibung
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.
Anwendung
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.
