4Isopropyltoluene

4-Isopropyltoluene, also known as p-cymene, is an organic compound with the chemical formula C10H14. It is a naturally occurring aromatic hydrocarbon found in essential oils of various plants, including cumin and thyme. Structurally, it is a toluene molecule with an isopropyl group attached at the para position. This arrangement gives it a distinct chemical identity and properties.

4-Isopropyltoluene is a colorless liquid with a characteristic aromatic odor. It is sparingly soluble in water but miscible with most organic solvents like ethanol and ether. Its boiling point is approximately 177 degrees Celsius. Due to its aromatic nature and the presence of the isopropyl substituent, it participates in various electrophilic aromatic substitution reactions.

Industrially, 4-isopropyltoluene is produced through the alkylation of toluene with propylene. It finds applications as a solvent, particularly in the paint and varnish industry. It also serves as a precursor in the synthesis of other chemicals, including p-cresol, which is used in the production of antioxidants and disinfectants. Its presence in essential oils contributes to their aroma and has led to its investigation for potential uses in perfumery and flavorings.
