Chemical Information
FooDB Name(1S,2R,4R)-1,2-Epoxy-p-menth-8-ene
Description1,2-epoxy-p-menth-8-ene, also known as limonene-1,2-epoxide or 1,2-epoxylimonene, is a member of the class of compounds known as oxepanes. Oxepanes are compounds containing an oxepane ring, which is a seven-member saturated aliphatic heterocycle with one oxygen and six carbon atoms. 1,2-epoxy-p-menth-8-ene is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 1,2-epoxy-p-menth-8-ene is a green tasting compound found in lemon and wild celery, which makes 1,2-epoxy-p-menth-8-ene a potential biomarker for the consumption of these food products.
