Description |
Methyl 2-nonenoate has a characteristic violet-like odor. May be obtained in quantitative yields by treating methyl P-chlorocaproate with sodium acetate, or by dehydrogenating the corresponding saturated ester. |
|
Chemical Properties |
Methyl-2-nonenoate has a characteristic green, violet-like odor |
|
Chemical Properties |
Colorless to slightly yellow liquid;strong violet-leaf odor. Stable; soluble in alco-hol. Combustible. |
|
Chemical Properties |
Methyl 2-Nonenoate is a colorless to pale yellow liquid with a green, floral note. It imparts freshness to floral fragrance compositions and is recommended as a substitute for methyl 2-octynoate.The synthesis consists of a condensation of heptanal withmalonic acid, decarboxylation, and subsequent esterification with methanol. |
