Description

Application

3-Methyl-1-butanol was used as standard in GC-MS analysis of volatile compounds produced by Rhizobacteria and Spanish Honeys.

Biochem/physiol Actions

3-Methyl-1-butanol is produced as a fusel alcohol in yeast fermentation. It is a naturally-produced fuel substitute that has advantages of acting as precursor for isoamyl acetate and replacement for gasoline.
