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

适用于高效液相色谱法、分光光度法和某些液-质联用应用
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.

Packaging

M-Bottle for Solvents
As a global leader in lab reagents, we are constantly looking for new ways to optimize the safety of our products. The newly developed 4L solvent bottle design features advanced sealing technology that eliminates leaks to make the handling of solvents safer and more convenient than ever before.
