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.
