2-Pentanol (IUPAC name: pentan-2-ol; also calledsec-amyl alcohol) is anorganicchemical compound. It is used as asolvent and an intermediate in the manufacturing of other chemicals. 2-Pentanol is a component of many mixtures ofamyl alcohols sold industrially. 2-Pentanol ischiral and thus can be obtained as either of twostereoisomers designated as (R)-(−)-2-pentanol and (S)-(+)-2-pentanol.
2-Pentanol has been detected in freshbananas bygas chromatography–mass spectrometry, at an abundance of 14.26±2.63 ppm.[2]
2-Pentanol can be manufactured byhydration ofpentene.[3]
