- The correct title of this article is n-Butylamine. The initial letter is shown capitalized due to technical restrictions.
n-Butylamine is an organic compound (specifically, an amine) with the formula CH3CH2CH2CH2NH2. This colourless liquid is one of the four isomeric amines of butame. At standard temperature and pressure, n-butylamine is a liquid having the fishy, ammonia-like odor common to amines. The liquid acquires a yellow colour upon storage in air. It is soluble is all organic solvents.
[edit] 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'-dibutylhiourea, a rubber vulcanization accelerator, and n-butylbenzenesulfonamide, a plasticizer in nylon.
