'''Pentane''' bost [[karbono]] [[atomo]] dituen [[hidrokarburo ase]]a da ([[formula kimiko]]a: C<sub>5</sub>H<sub>12</sub>). [[Petrolio]]aren eta [[gas natural]]aren osagaia da. [[Aire]]an oso erraz su hartzen duen [[fluido]] kolorgea da. [[Pisu espezifiko]]a 0,62 g/cm<sup>3</sup> du, eta 36 °C-an irakiten du. Ez da ongi disolbatzen [[ur]]etan eta [[alkohol]]ean, baina oso ongi [[bentzeno]]an eta [[eter]]rean. Petrolioaren [[destilazio]]z lortzen da. [[Disolbatzaile]] gisa erabiltzen da industrian, tenperatura oso txikiak neurtu behar dituzten termometroak egiteko, botikak ekoizteko bitarteko gisa, anestesiko gisa eta abar. Bera da pentanola lortzeko erabiltzen den lehengaia. Hiru isomero ditu: [[pentano lineal]]a, [[isopentano]]a eta [[neopentano]]a.
