A hydrocarbon compound found in citrus oils, related to limonene and other terpenes in essential oils.
From citrus plus the chemical suffix -ene (denoting a hydrocarbon with double bonds). Identified in the late 1800s during the chemical analysis of lemon and orange oils.
Citrene is part of the invisible aromatic alphabet—each essential oil is really a complex cocktail of different -ene compounds, and each one your nose detects separately, creating the complex 'lemon smell' that's actually dozens of molecules together.
