General description

3-methylbutanol (isoamyl alcohol) is a clear, colorless alcohol commonly used as an organic solvent . It can also be used in phenol-chloroform nucleic acid extraction and purification protocols, where it inhibits RNase activity and reduces foaming. Isoamyl alcohol can also be used for the removal of ethidium bromide from DNA purified by CsCl gradient ultracentrifugation.

Application

3-Methylbutanol (isoamyl alcohol) in combination with phenol and chloroform is used in extraction of RNA. It was used in the synthesis of oligo-RNAs using photocaged adenosine molecules.
3-Methylbutanol has been used as a component of phenol/chloroform/ isoamyl alcohol solution for DNA extraction from blood and from absorbing substrata based forensic samples and biofilms.
