Chemische Eigenschaften
2,6-Dimethyl-5-heptenal has a characteristic odor of melon and a corresponding taste.
Chemische Eigenschaften
2,6-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.
Occurrence
Reported found in lemon and lime peel oil, sudachi (Citrus sudachi H. ex. Shirai) and ginger.
Verwenden
It is used or fragrances designed to have a special fruity note tending towards melon, cucumber and pumpkin. It is mainly used perfuming agents.
synthetische
By condensation of isobutyric aldehyde with α-methylcrotonaldehyde, followed by par tial hydrogenation; also from methylheptenone through Darzen's reaction.
Aroma threshold values
Detection: 16 ppb
Taste threshold values
Taste characteristics at 50 ppm: green, melon, watermelon-rind, cucumber, with a waxy, chemical and floral nuance.
