n-Butylamine is an organic compound (specifically, an amine) with the formula CH₃CH₂CH₂CH₂NH₂. This colourless liquid is one of the four isomeric amines of butane, the others being sec-butylamine, tert-butylamine and isobutylamine. At standard temperature and pressure, n-butylamine is a liquid having the fishy, ammonia-like odor common to amines. The liquid acquires a yellow color upon storage in air. It is soluble in all organic solvents.

Uses

This compound is used as an ingredient in the manufacture of pesticides (such as thiocarbazides), pharmaceuticals, and emulsifiers. It is also a precursor for the manufacture of N,N'-dibutylthiourea, a rubber vulcanization accelerator, and n-butylbenzenesulfonamide, a plasticizer of nylon.
