Chemical Information
FooDB Name1-Phenyl-1,2-propanedione
Description1-Phenyl-1,2-propanedione, also known as acetyl benzoyl or phenyl methyl diketone, belongs to the class of organic compounds known as phenylpropanes. These are organic compounds containing a phenylpropane moiety. 1-Phenyl-1,2-propanedione is an extremely weak basic (essentially neutral) compound (based on its pKa). 1-Phenyl-1,2-propanedione is a buttery, honey, and pepper tasting compound. 1-Phenyl-1,2-propanedione has been detected, but not quantified in, coffee and coffee products. This could make 1-phenyl-1,2-propanedione a potential biomarker for the consumption of these foods.
