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.
