描述
Xi-5-dodecanolide, also known as (+/-)-6-heptyltetrahydro-2h-pyran-2-one or (+/-)-delta-heptyl-delta-valerolactone, is a member of the class of compounds known as delta valerolactones. Delta valerolactones are cyclic organic compounds containing an oxan-2- one moiety. Thus, xi-5-dodecanolide is considered to be a fatty ester lipid molecule. Xi-5-dodecanolide is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Xi-5-dodecanolide can be found in alcoholic beverages, fruits, herbs and spices, and milk and milk products, which makes xi-5-dodecanolide a potential biomarker for the consumption of these food products.
