What is trans-2-Hexen-1-ol?

Chemical properties

colourless liquid

Chemical properties

(E)-2-Hexen-1-ol occurs in many fruits and has a fruity, green odor, which is sweeter than that of the isomeric (Z)-3- hexen-1-ol and is, therefore, preferred in aroma compositions.

The Uses of trans-2-Hexen-1-ol

trans-2-Hexen-1-ol was used to evaluate the quality of protected designation of virgin olive oils by headspace solid-phase microextraction-gas chromatography using flame ionization detection and multivariate analysis. It was also used in encapsulation of vanadium catalysts in inorganic and hybrid matrices using sol-gel method.

What are the applications of Application

trans-2-Hexen-1-ol is A useful chemical to study olive oils and industrial practices of vanadium catalysts

Definition

ChEBI: 2-hexen-1-ol is a primary allylic alcohol that is 2-hexene in which a hydrogen at position 1 has been replaced by a hydroxy group. It has a role as a plant metabolite. It is an alkenyl alcohol and a primary allylic alcohol.
