Con il termine pentano ci si riferisce ad un qualunque alcano avente formula bruta C5H12 o ad una qualunque miscela di più composti corrispondenti a tale formula (isomeri strutturali) o per antonomasia all'isomero lineare, chiamato più propriamente n-pentano. Il pentano si ottiene per distillazione frazionata dal petrolio e dal gas naturale. A temperatura e pressione ambiente è un liquido incolore, volatile, dall'odore simile a quello della benzina. Sia il pentano che i suoi vapori sono estremamente infiammabili e formano con l'aria miscele potenzialmente esplosive. Trova impiego nella produzione di benzine, come solvente, nei processi di estrazione e nei termometri per basse temperature.Con la perdita di un atomo di idrogeno si ottiene il gruppo amile (o pentile).
