What is Dipentene？

Dipentene is a cyclic terpene hydrocarbon appearing as a colorless to pale yellow clear liquid with a characteristic citrus-like odor. It is insoluble in water but miscible with ethanol, ether, and most organic solvents. The compound is a racemic mixture of D- and L-limonene isomers and occurs naturally in various essential oils. It is widely used as a solvent, fragrance ingredient, and chemical intermediate.
