What is 1-Pentanol?

Pentan-1-ol is a short-chain primary fatty alcohol that is pentane in which a hydrogen of one of the methyl groups is substituted by a hydroxy group. It has been isolated from Melicope ptelefolia. It has a role as a plant metabolite and a human metabolite. It is a pentanol and a short-chain primary fatty alcohol.
