28069-72-9 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 28069-72-9 differently. You can refer to the following data:
1. CLEAR COLOURLESS LIQUID
2. (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
Different sources of media describe the Uses of 28069-72-9 differently. You can refer to the following data:
1. trans,cis-2,6-Nonadien-1-ol can be used as antimicrobial compositions for personal care products.
2. Food additive/natural product.

Check Digit Verification of cas no
The CAS Registry Mumber 28069-72-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,0,6 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 28069-72:
(7*2)+(6*8)+(5*0)+(4*6)+(3*9)+(2*7)+(1*2)=129
129 % 10 = 9
So 28069-72-9 is a valid CAS Registry Number.

Monosodio ethyl malonate on alkylation with 1-bromo-pent-2-yne (III) furnishes the diester (IV) which on decarbethoxylation with NaCl/DMSO, followed by LAH/EtOH reduction of the resultant ester (V), yields the carbinol (VI).Hydrogenation of VI in the presence of Lindlar's catalyst produces hept-4Z-en-1-ol (VII), which on pyridinium chlorochromate oxidation gives the aldehyde (VIII).Wittig-Horner reaction on VIII using ethyl diethylphosphonoacetate produces the dienoate (IX), which on LAH/EtOH reduction followed by oxidation with Corey's reagent, affords the title compound(I).
