Natural Product Identification
Common Name9,10-Epoxyoctadecanoic acid
Description(9R,10S)-9,10-epoxy-18-hydroxyoctadecanoic acid, also known as (9R,10S)-18-hydroxy-9,10-epoxystearic acid or 18-hydroxy-(9R,10S)-epoxy-octadecanoic acid, belongs to the class of organic compounds known as medium-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 4 and 12 carbon atoms (9R,10S)-9,10-epoxy-18-hydroxyoctadecanoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 9,10-Epoxyoctadecanoic acid is expected to be in Cannabis as all living plants are known to produce and metabolize it.
