Odor description: grapefruit, tart, slightly woody

A sesquiterpene ketone with the intense, juicy aroma of grapefruit—the key molecule behind the fruit’s characteristic scent. Despite its citrus profile, it stands out for exceptional longevity rarely found in this family. In a composition it carries a refined, slightly bitter citrus glow from top to base. Pairs well with vetiver, cedar, bergamot, and rhubarb notes.
