A hydrocarbon compound found in essential oils, particularly from citrus fruits and turpentine, used in fragrances and solvents.
From 'di-' (two) and 'pentene' (a five-carbon hydrocarbon molecule), reflecting its chemical structure of two linked pentene units. The term comes from analyzing terpene chemistry in plant oils.
Dipentene is why lemon essential oil smells lemony—it's one of the main aromatic molecules plants use to attract bees and warn off pests, and humans later discovered we liked the smell!
