Cumene, or isopropylbenzene, is an aromatic hydrocarbon commonly used as an industrial solvent and in the production of phenol and acetone. It is a colorless liquid with a characteristic odor, found in crude oil and produced from petroleum. In food and spice applications, cumene is not typically used directly but may be present as a trace contaminant in some essential oils. Its sensory characteristics include a sweet, aromatic scent. Cumene is significant in chemical synthesis, particularly in the cumene process for phenol production, which is vital for plastics and resins.
