Application

3-Methylhexane can be used as a model alkane to study:
  • Cu-catalyzed hydrocarboxylation of simple alkanes to corresponding branched monocarboxylic acids in aqueous medium at low-temperature.
  • Au-catalyzed oxygenation of alkanes with H2O2 in acetonitrile.
  • FeCI3 catalyzed photooxygenation of simple alkanes to corresponding alcohols in presence of atmospheric O2.

3-Methylhexane is one of the isomer of heptane. It can be used as a reactant in the synthesis of dimethyl isomers (dimethyl pentanes) using Pt/WZA catalyst.
