2,3-Dihydrobenzofuran

Description

2,3-Dihydrobenzofuran, also known as coumaran or dihydrocoumarone, belongs to the class of organic compounds known as coumarans. Coumarans are compounds containing the coumaran skeleton, which consists of a benzene ring fused to a 2,3-dihydrofuran ring. 2,3-Dihydrobenzofuran has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make 2,3-dihydrobenzofuran a potential biomarker for the consumption of these foods. 2,3-Dihydrobenzofuran is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on 2,3-Dihydrobenzofuran.
