n-Butylamine is an organic compound (specifically, an amine) with the formula CH₃(CH₂)₃NH₂. This colourless liquid is one of the four isomeric amines of butane, the others being sec-butylamine, tert-butylamine, and isobutylamine. It 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. Its vapours are heavier than air and it produces toxic oxides of nitrogen during combustion.{{Cite web|last=PubChem|title=Butylamine|url=https://pubchem.ncbi.nlm.nih.gov/compound/8007|access-date=2022-02-15|website=pubchem.ncbi.nlm.nih.gov|language=en}}
