What is Butylamine?

Butylamine (CAS 109-73-9) has many isomerides. To make its name clear and unique, we use n-Butylamine as recommend by  Wikipedia. n-Butylamine is an organic amine compound with the formula CH3CH2CH2CH2NH2(C4H11N). This colorless liquid is one of the four isomeric amines of butane, the others being sec-butylamine(CAS 33966-50-6) , tert-butylamine(CAS 75-64-9) and isobutylamine(CAS 78-81-9 ). 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. Like other simple aliphatic amines, n-butylamine is a weak base with a pKa of 10.59 in its protonated form.

1-Aminobutane is the intermediate for the herbicide butralin. It is mainly used to synthesize medicine, dyestuff, and pesticide.

n-Butylamine applications

n-Butylamine is an important intermediate 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.

N-Butylamine was used in the synthesis of Fengabine.
