Application

3-Methyl-1-butanol has been used in the preparation of bioactive beads (BABs) with uniform size for transformation.

Biochem/physiol Actions

3-Methyl-1-butanol is a pentanol isomer useful in biofuels. It is used as a starting material for the production of isoamyl acetate, a flavoring agent applicable in the food industry. 3-Methyl-1-butanol shows anti-fungal action by inhibiting the hyphal formation and reducing biofilm formation in Candida albicans. It is also used in DNA extraction protocols.
