Calone

Calone or methylbenzodioxepinone, trade-named Calone 1951, is an organic compound with the formula CH
3C
6H
3(OCH
2)
2CO. A white solid, it is a derivative of 4-methylcatechol. In the fragrance industry it is known as "watermelon ketone" or simply "calone".^[1]

It was discovered by Pfizer in 1966. It is used to give the olfactory impression of a fresh seashore through the marine and ozone nuances (specifically, as fresh, watery, clean, melon, green, marine, and ozone).^[2] Calone is similar in structure to brown algae pheromones like ectocarpene and is also distantly related in structure to the benzodiazepine class of sedatives.^[3]

Calone is an unusual chemical compound which has an intense "sea-breeze" note with slight floral and fruit 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.^[4] Swiss company Firmenich later released Cascalone, a sweet, watery version of calone with a transparent floral signature.^[5]
