Chemical Information
FooDB Name3,4-Dimethyl-1,2-cyclopentanedione
Description3,4-Dimethyl-1,2-cyclopentanedione, also known as fema 3268, 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. 3,4-Dimethyl-1,2-cyclopentanedione is an extremely weak basic (essentially neutral) compound (based on its pKa). 3,4-Dimethyl-1,2-cyclopentanedione is a sweet, anise, and balsam tasting compound. 3,4-Dimethyl-1,2-cyclopentanedione has been detected, but not quantified in, coffee and coffee products. This could make 3,4-dimethyl-1,2-cyclopentanedione a potential biomarker for the consumption of these foods.
