Natural Product Identification
Common Name3-Ethyl-5-methyl-1,2-cyclopentanedione
Description3-Ethyl-5-methyl-1,2-cyclopentanedione, also known as fema 3454, belongs to the class of organic compounds known as cyclic ketones. These are organic compounds containing a ketone that is conjugated to a cyclic moiety. 3-Ethyl-5-methyl-1,2-cyclopentanedione is an extremely weak basic (essentially neutral) compound (based on its pKa). 3-Ethyl-5-methyl-1,2-cyclopentanedione is a malty tasting compound. Outside of the human body, 3-Ethyl-5-methyl-1,2-cyclopentanedione has been detected, but not quantified in, coffee and coffee products. This could make 3-ethyl-5-methyl-1,2-cyclopentanedione a potential biomarker for the consumption of these foods.
