(Z)-11-[(2R,3S)-3-pentyloxiran-2-yl]undec-9-enoic acid

(±)-cis-12,13-Epoxy-9(Z)-octadecenoic Acid, an isomer of (-)-Vernolic Acid (V128710). a fatty acid that is monounsaturated and contains an epoxide. It is It is the cis epoxide derived from the C12–C13 alkene of linoleic acid, and an isomer of coronaric acid. Vernolic acid is the key component in vernonia oil, which is produced in abundance by the genera Vernonia and Euphorbia and is a potentially useful biofeedstock.

ChEBI: (+)-vernolic acid is an optically active form of vernolic acid having (12S,13R)-configuration. It is a vernolic acid and an oxylipin. It is an enantiomer of a (-)-vernolic acid.
