Metabolite Identification
Common Name3-Methyl-2-butanol
Description3-Methyl-2-butanol, also known as (CH3)2chch(OH)CH3 or 1,2-dimethylpropanol, 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). 3-Methyl-2-butanol is an extremely weak basic (essentially neutral) compound (based on its pKa). 3-Methyl-2-butanol (IUPAC name, commonly called sec-isoamyl alcohol) is an organic chemical compound. 3-Methyl-2-butanol is a fruity tasting compound. Outside of the human body, 3-methyl-2-butanol has been detected, but not quantified in, several different foods, such as alcoholic beverages, citrus, fruits, and pomes. This could make 3-methyl-2-butanol a potential biomarker for the consumption of these foods.
