Popis

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.

Application

High-purity, multipurpose solvent, tested for suitability in:

• HPLC with gradient analysis
• Spectrophotometry
• Residual testing
• LC-MS applications

Used as a solvent/reagent to determine total phenols content, anti-DPPH activity and the content of antioxidants in honeybee drone blood homogenate (DBH) samples.

Meets ACS specifications.
