Methylamine is the chemical compound with a formula of CH3NH2. It is a derivative of ammonia, wherein one H atom is replaced by a methyl group. It is the simplest primary amine. It is usually sold as solutions in methanol (2M), ethanol (8M), THF (2M), and water (40%), or as the anhydrous gas in pressurized metal containers. It has a strong odour similar to rotten fish. Methylamine is used as a building block for the synthesis of other organic compounds. It is on the DEA watchlist for chemical precursors because of clandestine use in manufacture of the drug MDMA (ecstasy) and methamphetamine.
Additional recommended knowledge
The hydrochloride salt of methylamine, methylammonium chloride, CH3NH3Cl, is a colourless powder that can be converted to the amine.
Although methylamine is a gas at room temperature, liquid methylamine can be used as a solvent analogous to liquid ammonia. It shares some of the properties of liquid ammonia, but is better for dissolving organic substances, same as methanol is better than water.
CH3OH + NH3 → CH3NH2 + H2O
NH4Cl + H2CO → CH2NH·HCl + H2O
CH2NH·HCl + H2CO + H2O → CH3NH2 + HCOOH
