7-Methyl-2H-1,5-benzodioxepin-3(4H)-one Use and Manufacturing

Uses

Calone or methylbenzodioxepinone, trade-named Calone 1951, also known in the industry as "watermelon ketone", was discovered by Pfizer in 1966. It is used to give the olfactory impression of a fresh seashore through the marine and ozone nuances. Calone is similar in structure of certain alicyclic C11-hydrocarbons like ectocarpene, excreted by some species of brown algae as pheromones.Calone is an unusual odorant which has an intense "sea-breeze" note with slight floral overtones. It has been used as a scent component since the 1980s for its watery, fresh, ozone accords, and as a more dominant note in several perfumes of the marine trend, beginning in the 1990s.
