Cannabis Compound Identification
Common Nameo-Cymene
Description1-Isopropyl-2-methylbenzene also known as o-Cymene, belongs to the class of organic compounds known as cumenes. These are aromatic compounds containing a prop-2-ylbenzene moiety. o-Cymene is an organic compound classified as an aromatic hydrocarbon. Its structure consists of a benzene ring ortho-substituted with a methyl group and an isopropyl group. It is a flammable colorless liquid which is nearly insoluble in water but soluble in organic solvents. o-Cymene has been detected, but not quantified in citrus. o- In addition to o-cymene, there are two other geometric isomers called m-cymene, in which the alkyl groups are meta-substituted, and p-cymene, in which they are para-substituted. p-Cymene is the most common and only natural isomer. The three isomers form the group of cymenes. Cymenes can be produced by alkylation of toluene with propylene ( Ref:DOI ). o-Cymene has been reported to be present as a volatile component in cannabis samples (PMID: 26657499 ).
