| Chemical Properties |
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. |
| Chemical Properties | 2,6-Dimethyl-5-heptenal has a characteristic odor of melon and a corresponding taste. |
| Occurrence | Reported found in lemon and lime peel oil, sudachi (Citrus sudachi H. ex. Shirai) and ginger. |
| 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. |
| Trade name | Melonal (Givaudan), Melomor (Aromor). |
| Safety Profile | skin and eye irritant. When heated to decomposition it emits acrid smoke and irritating fumes. |
