p-Cymene is a naturally occurring compound, although it has two further geometric isomers, m-cymene (with meta-substituted alkyl groups) and o-cymene (with ortho-substituted alkyl groups) which do not occur naturally. p-Cymene is related to the monoterpenes. Monoterpenes themselves belong to the “terpenes”, a larger class of organic compounds, which are the most representative components of essential oils. chemical structure of p-cymene, indicating the benzene ring with methyl and isopropyl substitutions.
p-Cymene is an alkyl aromatic hydrocarbon mainly used to study oxidation reactions under various conditions to synthesize highly valuable intermediates and building-blocks such as cymene hydroperoxide, 4-methyl acetophenone, 4-isopropyl benzyl alcohol, 4-isopropyl benzaldehyde and 4-isopropyl benzoic acid etc.
Medicinally, p-cymene is used to prevent coughs and eliminate phlegm as well as being a flavouring agent, and being used in the production of fungicides and pesticides. It is considered to be “generally recognised as safe” (GRAS) by the U.S. Food and Drug Administration. Its potential in the prevention of protein glycation mediated diabetic complications has also been confirmed, and it has been suggested as an in vivo antioxidant compound due to its ability to reduce the formation of oxygen and nitrogen reactive species, acting as a potential neuroprotective agent in the brain. Therefore, it could be involved in the treatment of oxidative stress related diseases.
