| Description | 3,4-Dihydro-2,2,5,7,8-pentamethyl-2H-1-benzopyran-6-ol belongs to the class of organic compounds known as 2,2-dimethyl-1-benzopyrans. These are organic compounds containing a 1-benzopyran moiety that carries two methyl groups at the 2-position. 3,4-Dihydro-2,2,5,7,8-pentamethyl-2H-1-benzopyran-6-ol has been detected, but not quantified in, fats and oils. This could make 3,4-dihydro-2,2,5,7,8-pentamethyl-2H-1-benzopyran-6-ol a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 3,4-Dihydro-2,2,5,7,8-pentamethyl-2H-1-benzopyran-6-ol. |
