Pentylamine exhibits reactions typical of other simple alkyl amines, i.e. protonation, alkylation, acylation, condensation with carbonyls. Like other simple aliphatic amines, pentylamine is a weak base: the pK_a of [CH₃(CH₂)₄NH₃]⁺ is 10.21.<ref>{{cite journal|author=H. K. Hall, Jr.|year=1957|journal=J. Am. Chem.
