H3CNH2

H3CNH2, more commonly known as methylamine, is an organonitrogen compound with the chemical formula CH3NH2. It is the simplest primary amine, consisting of a methyl group attached to an amino group. Methylamine is a colorless gas at room temperature with a strong, unpleasant odor resembling that of fish. It is highly soluble in water and most organic solvents.

Methylamine is a versatile chemical intermediate used in the synthesis of a wide range of products. It is a key building block for pharmaceuticals, agrochemicals, and pesticides. For example, it is used in the production of methamphetamine and the insecticide carbaryl. Methylamine is also employed in the manufacturing of dyes, solvents, and surfactants. Its reactivity stems from the nucleophilic nature of the nitrogen atom, allowing it to participate in various organic reactions.

Industrially, methylamine is primarily produced through the reaction of ammonia with methanol over an acidic catalyst. This process yields a mixture of methylamine, dimethylamine, and trimethylamine, which are then separated by distillation. Methylamine is a flammable gas and requires careful handling due to its toxicity and corrosive properties. Exposure can cause irritation to the eyes, skin, and respiratory tract.
