Watermelon Ketone Usage And Synthesis

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.

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.

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

Non flammable

Trade name

Aquamor (Aromor), Calone® (Firmenich), Ganone (Agan).
