Watermelon Ketone(Cas 28940-11-6) Usage
|
Uses |
7-Methyl-2H-1,5-benzodioxepin-3(4H)-one has shown gender-specific reduction in overall olfactory impact of stress-related odor by cross adaptation in human apocrine secretion. |
|
Description |
Watermelon Ketone, also known as calone or methylbenodioxepinone is a hydrocarbon compound with similar structure of certain alicyclic C11-hydrocarbons such as ectocarpene. It is a flavor and fragrance chemical compound with special odorant. It was used as a scent component since the 1980s for its watery, fresh, ozone accords. It was later supplemented into several perfumes of the marine trend, beginning in the 1990s. |
|
Chemical Properties |
Watermelon Ketone is a white powder with a fresh marine odor, mp 35–41°C. It is used to create fresh aquatic marine notes in perfume oils for many applications, for example, for fine fragrances, soaps, and shower gels. |
|
Preparation |
The material is prepared by etherification of 4-methylpyrocatechol with two equivalents of alkyl 2-bromoacetate and subsequentDieckmann condensation followed by hydrolysis and decarboxylation. |
|
Flammability and Explosibility |
Nonflammable |
