Descripción

Descripción general

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.

Aplicación

Methanol is used as a solvent:

• In the mobile phase during the reversed phase for high-performance liquid chromatography (HPLC) analysis.
• To prepare the stock solution of Fluorescein dye.

Envase
