Methylamine CH3NH2 is an organic ammonia derivative, a primary aliphatic amine. Under normal conditions, methylamine is a colorless gas with an ammonia odor. Methylamine is a typical primary amine. Methylamine forms salts with acids. Reactions with aldehydes and acetals lead to Schiff bases. When reacted with esters or acyl chlorides it gives amides. As a rule, it is used in the form of solutions: 40% (wt%) in water, methanol, ethanol or THF. It has good solubility in water.
