Description

General description

Methanol is an alcohol. Its conversion to C₂-C₁₀ hydrocarbons by employing a new class of shape-selective zeolites has been reported. Its oxidation on Ru-Pt catalyst system by ruthenium ad-atoms has been proposed.

Application

Methanol was used in the following studies:

• Colony forming unit-fibroblast assay of bone marrow mononuclear cells.[1]
• As solvent for the preparation of extracts of hyphae of Aspergillus for the estimation of gliotoxin by reversed phase-HPLC.[2]
• Immunofluorescence studies.[3]

Packaging

This product is also available in glass bottles.
