What is Monomethylamine?
Monomethylamine (MMA) is an organic compound derived from ammonia, where one hydrogen atom is replaced by a methyl group (CH₃). It is a colorless gas at room temperature with a pungent odor, similar to ammonia. Monomethylamine is typically available as an aqueous solution in concentrations ranging from 40% to 60%.
