Beschreibung

Allgemeine Beschreibung

Methanol is an alcohol. Its conversion to C₂-C₁₀ hydrocarbons by employing a new class of shape-selective zeolites has been reported.[1] Its oxidation on Ru-Pt catalyst system by ruthenium ad-atoms has been proposed.[2]

Anwendung

Methanol was used in the following studies:

• Colony forming unit-fibroblast assay of bone marrow mononuclear cells.[3]
• As solvent for the preparation of extracts of hyphae of Aspergillus for the estimation of gliotoxin by reversed phase-HPLC.[4]
• Immunofluorescence studies.[5]

Verpackung

Dieses Produkt ist auch in Glasflaschen erhältlich.
