Used as a solvent in laboratories and industrial processes, particularly in high-performance liquid chromatography (HPLC) due to its purity and consistent composition. Commonly employed in fuel cells as a source of hydrogen through methanol reforming. Serves as a cleaning agent for electronic components because it evaporates quickly and leaves minimal residue. Utilized in the synthesis of biodiesel by transesterification of fats and oils. Also used as a preservative in some analytical reagents and biological samples.
