Monomethylamine (MMA)

Monomethylamine is a basic alkylamine and the simplest primary amine. It is a colorless gas co-produced with dimethylamine (DMA) and trimethylamine (TMA). It has a strong ammoniacal or fishy odor and is sold as an anhydrous gas in pressurized cylinders or as aqueous solution. It is a building block for the synthesis of many other commercial compounds.
