CIS-2-PENTEN-1-OL Usage And Synthesis

Chemical Properties

clear colorless to pink-beige liquid

Chemical Properties

Colorless liquid; green diffusive aroma.

Occurrence

Reported found in asparagus, bilberry, blueberry, crayfish, kiwi fruit, petitgrain grapefruit oil, angelica seed oil (0.30%).

Uses

cis-2-Penten-1-ol is used in the preparation of 1-bromo-pent-2-ene by reacting with phosphorus tribromide and pyridine. Further, it is a banana flavored compound.

Definition

ChEBI: (Z)-2-penten-1-ol is a 2-penten-1-ol in which the double bond has (Z)-configuration. It is a volatile compound found in green tea, virgin olive oil, and broccoli. It is also used as a fragrance ingredient cosmetics, shampoos and soaps as well as in non-cosmetic products such as household cleaners and detergents. It has a role as a human metabolite, a fragrance, a plant metabolite, an insect attractant, a flavouring agent and a mammalian metabolite. It is a 2-penten-1-ol and a volatile organic compound.

Aroma threshold values

Medium strength odor, green type; recommend smelling in a 10.00% solution or less.

General Description

cis-2-Penten-1-ol is also known as banana flavoured compound. It was found to reduce the efficiency of sex pheromone lures in trapping male moths in a proof long-range field trapping experiment. Kinetics of gas-phase reactions of NO3 radical with cis-2-penten-1-ol was investigated using relative rates technique.
