2-Methyl-1-butanol (IUPAC name, also called active amyl alcohol) is an organic chemical compound.
It is one of the components of the aroma of Tuber melanosporum, the black truffle.[citation needed]
Uses
It is used as a solvent and an intermediate in the manufacture of other chemicals. 2-Methyl-1-butanol is a component of many mixtures of amyl alcohols sold industrially.
Reactions
2-Methyl-1-butanol can be derived from fusel oil (because it occurs naturally in fruits such as grapes[3]) or manufactured by either the oxo process or via the halogenation of pentane.[2]
