p-Cymene is a naturally occurring aromatic organic compound.

p-Cymene is insoluble in water, but miscible with organic solvents.

In addition to p-cymene, two less common geometric isomers are o-cymene, in which the alkyl groups are ortho-substituted, and m-cymene, in which they are meta-substituted.

Significant amounts are formed in sulfite pulping process from the wood terpenes.

This half-sandwich compound is prepared by the reaction of ruthenium trichloride with the terpene α-phellandrene.
