Primary alcohols are compounds comprising the primary alcohol functional group, with the general structure RCOH (R=alkyl, aryl). Thus, (s)-2-methyl-1-butanol is considered to be a fatty alcohol lipid molecule (s)-2-methyl-1-butanol is soluble (in water) and an extremely weak acidic compound (based on its pKa). (s)-2-methyl-1-butanol can be synthesized from isopentane (s)-2-methyl-1-butanol can also be synthesized into 2-methylbutyl acetate and 2-methylbutyl decanoate (s)-2-methyl-1-butanol is a malt tasting compound and can be found in a number of food items such as turmeric, salmonberry, garden cress, and horseradish tree, which makes (s)-2-methyl-1-butanol a potential biomarker for the consumption of these food products (s)-2-methyl-1-butanol can be found primarily in feces (s)-2-methyl-1-butanol exists in all eukaryotes, ranging from yeast to humans. active-Amyl alcohol C5H12O 88.1482 88.088815006 2-methylbutan-1-ol 2-methyl-1-butanol 137-32-6 CCC(C)CO InChI=1S/C5H12O/c1-3-5(2)4-6/h5-6H,3-4H2,1-2H3 QPRQEDXDYOZYLA-UHFFFAOYSA-N belongs to the class of organic compounds known as primary alcohols.
