Application

Methanol (MeOH) has been used as an eluent in the HPLC estimation of malondialdehyde in plasma, which is an indicator of oxidative stress.It may be used in the following studies: Colony forming unit-fibroblast assay of bone marrow mononuclear cells. As solvent for the preparation of extracts of hyphae of Aspergillus for the estimation of gliotoxin by reversed phase-HPLC.Immunofluorescence studies.To compose eluent for the ion-pair reverse-phase HPLC isolation of nucleotides and their decomposition products.

General description

Thermochemical conversion of methanol to C2-C10 hydrocarbons in the presence of shape-selective zeolites has been reported. Its oxidation on Ru-Pt catalyst system by ruthenium ad-atoms has been proposed.
