Chemical Information
FooDB Namexi-2-Pentanol
Description2-Pentanol, also known as 1-methylbutanol or 2-hydroxypentane, belongs to the class of organic compounds known as secondary alcohols. Secondary alcohols are compounds containing a secondary alcohol functional group, with the general structure HOC(R)(R') (R,R'=alkyl, aryl). 2-Pentanol is a green tasting compound. 2-Pentanol has been detected, but not quantified in, a few different foods, such as alcoholic beverages, fruits, and milk and milk products. This could make 2-pentanol a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 2-Pentanol.
