1-Aminopentane is an organic compound with the formula CH₃(CH₂)₄NH₂. It is used as a solvent, as a raw material in the manufacture of a variety of other compounds, including dyes, emulsifiers, and pharmaceutical products,^[1] and as a flavoring agent.^[2]^[3]

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.^[4]
