Propylamine, also known as n-propylamine, is an amine with the chemical formula CH₃(CH₂)₂NH₂.{{Cite web|url=https://pubchem.ncbi.nlm.nih.gov/compound/Propylamine|title = Propylamine}} It is a colorless volatile liquid.Karsten Eller, Erhard Henkes, Roland Rossbacher, Hartmut Höke "Amines, Aliphatic" in Ullmann's Encyclopedia of Industrial Chemistry, Wiley-VCH, Weinheim, 2005. {{doi|10.1002/14356007.a02_001}}

Propylamine is a weak base. Its K_b (base dissociation constant) is 4.7 × 10⁻⁴.
