Chemical Information
FooDB Name3,4-Dihydro-2H-1-benzopyran-2-one
Description3,4-Dihydro-2H-1-benzopyran-2-one, also known as dihydrocoumarin or 1,2-benzodihydropyrone, belongs to the class of organic compounds known as 3,4-dihydrocoumarins. These are 3,4-dihydrogenated coumarins. Coumarin is a bicyclic compound that are 1-benzopyran carrying an oxo group at the 2-position. 3,4-Dihydro-2H-1-benzopyran-2-one exists in all living organisms, ranging from bacteria to humans. 3,4-Dihydro-2H-1-benzopyran-2-one is a sweet, almond, and cinnamon tasting compound. 3,4-Dihydro-2H-1-benzopyran-2-one has been detected, but not quantified in, several different foods, such as green vegetables, pulses, sour cherries (Prunus cerasus), and tarragons (Artemisia dracunculus). This could make 3,4-dihydro-2H-1-benzopyran-2-one a potential biomarker for the consumption of these foods. Based on a literature review a small amount of articles have been published on 3,4-Dihydro-2H-1-benzopyran-2-one.
