| | TRANS,CIS-2,6-NONADIEN-1-OL Usage And Synthesis |
| 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. | | Chemical Properties | CLEAR COLOURLESS LIQUID | | Uses | Food additive/natural product. | | Uses | trans,cis-2,6-Nonadien-1-ol can be used as antimicrobial compositions for personal care products. | | 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is a primary allylic alcohol that is (2E,6Z)-nona-2,6-diene in which a hydrogen at position 1 has been replaced by a hydroxy group.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. | | Synthesis Reference(s) | Synthesis, p. 528, 1978 DOI: 10.1055/s-1978-24798 | | Hazard | Low toxicity by ingestion and skin contact.
