Description

General description

Methanol (MeOH) is an organic solvent with a wide range of industrial applications. It is the main component of lithium batteries. It can be prepared by hydrogenation of CO₂ under various conditions. MeOH is a toxic alcohol employed for denaturing ethyl alcohol. A study reports the preparation of biodiesel from canola oil using methanol under supercritical conditions.

Methanol is an alcohol. Its thermochemical conversion 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.

Application

Methanol (MeOH) 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.
• As eluent in the HPLC estimation of malondialdehyde in plasma, which is an indicator of oxidative stress.

Suitable for HPLC, spectrophotometry, and some LC-MS applications
