Chemical Information
FooDB Name1-Isopropyl-4-methylbenzene
Descriptionp-Cymene, also known as p-cymol or isopropyltoluene, belongs to the class of organic compounds known as aromatic monoterpenoids. These are monoterpenoids containing at least one aromatic ring.Its structure consists of a benzene ring para-substituted with a methyl group and an isopropyl group. Thus, p-cymene is considered to be an isoprenoid lipid molecule. p-Cymene is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.It has a role as a plant metabolite, a volatile oil component. p-Cymene
