Calone
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 to brown algae pheromones like ectocarpene.

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. In 2014, Plummer et al. reported the synthesis and fragrance properties of several related aliphatic analogues. [1]
