Pentylamine is an organic compound with the formula CH<sub>3</sub>(CH<sub>2</sub>)<sub>4</sub>NH<sub>2</sub>. 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, and as a flavoring agent.
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<sub>a</sub> of [CH<sub>3</sub>(CH<sub>2</sub>)<sub>4</sub>NH<sub>3</sub>]<sup>+</sup> is 10.21.
