TRANS,CIS-2,6-NONADIEN-1-OL Usage And Synthesis

Chemical Properties

CLEAR COLOURLESS LIQUID

Chemical Properties

(2E,6Z)-2,6-Nonadien-1-ol occurs, for example, in cucumber oil, violet leaf oil, and violet blossom oil. It is a colorless liquid with an intense, heavy, fatty, green odor, reminiscent of violet leaves. The starting material for the synthesis of (2E,6Z)-2,6-nonadien-l-ol is (Z)-3-hexen- 1-ol, which is converted via its halide into the corresponding Grignard reagent. The Grignard reagent is reacted with acrolein to give 1,6-nonadien-3-ol, which is converted into (2E,6Z)-2,6-nonadien-l-ol by allylic rearrangement.
Nonadienal is a powerful fragrance substance. It is used in fine fragrances to create refined violet odors and to impart interesting notes to other blossom compositions. In aroma compositions, it is used for fresh, green cucumber notes.

Uses

trans,cis-2,6-Nonadien-1-ol can be used as antimicrobial compositions for personal care products.

Uses

Food additive/natural product.

Definition

ChEBI: (2E,6Z)-nona-2,6-dien-1-ol is a primary allylic alcohol that is (2E,6Z)-nona-2,6-diene in which a hydrogen at position 1 has been replaced by a hydroxy group. It has a role as a flavouring agent, a plant metabolite and a fragrance. It is an alkenyl alcohol, a volatile organic compound, a primary allylic alcohol and a medium-chain primary fatty alcohol.
