7786-44-9 Usage
Description
2,6-Nonadien-l-ol has a powerful, green, vegetable odor. May be prepared from naturally occurring 3-hexen-l-ol (leaf alcohol) to yield the natural trans-2-cis form or from synthetic hexenol to yield the trans-2-trans form.
Chemical Properties
2,6-Nonadien-1-ol has a powerful, green, vegetable odor.
Occurrence
Originally isolated in the oils of violet leaf and violet flowers (hence, the name “violet leaf alcohol”); also in
cucumber, cornmint oil, prickly pear and malt
Taste threshold values
Taste characteristics at 10 ppm: melon, watermelon, violet, mushroom-like with apple and rosy nuances.
Synthesis
Prepared from naturally occurring 3-hexen-1-ol (leaf alcohol) to yield the natural trans-2-cis form or from synthetic
hexanol to yield the trans-2-trans form
Check Digit Verification of cas no
The CAS Registry Mumber 7786-44-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7786-44:
(6*7)+(5*7)+(4*8)+(3*6)+(2*4)+(1*4)=139
139 % 10 = 9
So 7786-44-9 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).
