Description

General description

Methanol, also known as Methyl alcohol, is a colorless organic solvent commonly used to dissolve substances with high and medium polarity. It is also used as a starting material/solvent for synthesis. It is commonly used as an elution solvent for chromatography.

Application

Methanol is used as:

• A solvent to prepare the Mobile phase for LC-MS/MS analysis.
• A solvent or reagent in chemical synthesis
• A solvent in work-up phase of chemical synthesis
• A disinfectant to clean laboratory space.
