General description

2-Methyl-1-propanol (Isobutyl alcohol) is widely used organic solvent.

Application

2-Methyl-1-propanol (Isobutyl alcohol) may be used to prepare the isobutyl alcohol-benzene solution for use in the quantification of inorganic phosphates. It may be used for the estimation of phosphate (inorganic phosphorous) by a colorimetric method.

The limited supply of fossil resources demands the development of renewable alternatives to petroleum-based products. Here, biobased higher alcohols such as isobutanol are versatile platform molecules for the synthesis of chemical commodities and fuels. Currently, their fermentation-based production is limited

Isobutanol is an excellent alternative biofuel. Fermentative production of isobutanol had been realized in several microorganisms by combining branched-chain amino acids synthetic pathway and Ehrlich pathway. In contrast to using plasmid overexpression and inducible promoters, genetically stable Escherichia coli strains
