Metabolite Identification
Common Name2,3,4-Trimethyl-3-pentanol
Description2,3,4-Trimethyl-3-pentanol belongs to the class of organic compounds known as tertiary alcohols. Tertiary alcohols are compounds in which a hydroxy group, -OH, is attached to a saturated carbon atom R3COH (R not H ). 2,3,4-Trimethyl-3-pentanol is a fruity tasting compound. 2,3,4-Trimethyl-3-pentanol has been detected, but not quantified in, alcoholic beverages and fruits. This could make 2,3,4-trimethyl-3-pentanol a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2,3,4-Trimethyl-3-pentanol.
