Methylamine boleh digunakan untuk membuat racun perosak, farmaseutikal, pemecut pemvulkanan getah, pewarna, bahan letupan, kulit, petroleum, surfaktan, dan resin penukar ion, pelucut cat, dan salutan serta bahan tambahan. Ia merupakan bahan mentah yang penting untuk pembuatan racun perosak dimethoate, carbaryl, dan chlordimeform.
Methylamine is an important kind of fatty amines organic chemicals and is used in a variety of industries such as manufacture of dyestuffs, treatment of cellulose, acetate rayon, as fuel additive, rocket propellant, and leather tanning processes. It can be used in the synthesis of the N-methyl-chloroacetamide that is the intermediate of the organic phosphorus insecticide dimethoate and omethoate; synthesis of the intermediate of the monocrotophos, α-chloro acetoacetyl methylamine; synthesis of the intermediates of carbamate pesticide, carbamoyl chloride and methyl isocyanate; as well as the synthesis of other pesticides varieties such as formamidine, amitraz, and tribenuron, etc. In addition, it can also be used in medicine, rubber, dyes, leather industry and photosensitive materials.
