2,6-Dimethyl-5-heptenal Usage And Synthesis
Chemical Properties2,6-Dimethyl-5-hepten-1-al was identified in ginger. It is a yellow liquid with a powerful, green, cucumber-like, and melon odor. It can be prepared by Darzens reaction of 6-methyl-5-hepten-2-one with ethyl chloroacetate. The intermediate glycidate is saponified and decarboxylated to yield the title compound.
It is used in many fragrance types and is invaluable in the creation ofmelon and cucumber notes.
Chemical Properties2,6-Dimethyl-5-heptenal has a characteristic odor of melon and a corresponding taste.
OccurrenceReported found in lemon and lime peel oil, sudachi (Citrus sudachi H. ex. Shirai) and ginger.
PreparationBy condensation of isobutyric aldehyde with α-methylcrotonaldehyde, followed by par tial hydrogenation; also from methylheptenone through Darzen's reaction.
Aroma threshold valuesDetection: 16 ppb
Taste threshold valuesTaste characteristics at 50 ppm: green, melon, watermelon-rind, cucumber, with a waxy, chemical and floral nuance.
Trade nameMelonal (Givaudan), Melomor (Aromor).
Safety Profileskin and eye irritant. When heated to decomposition it emits acrid smoke and irritating fumes.
