Used as a solvent in industrial and laboratory applications where a polar, water-miscible medium is required. Commonly applied in liquid chromatography, especially in reversed-phase HPLC, due to its ability to dissolve a wide range of organic compounds and its compatibility with UV detection. Serves as a reagent in chemical synthesis, including esterification and transesterification reactions, such as biodiesel production. Employed as a cleaning agent for equipment and surfaces in pharmaceutical and electronics manufacturing. Also utilized in fuel applications, such as in methanol fuel cells or as a component in gasoline blends to improve combustion and reduce emissions. Its low freezing point makes it useful as an antifreeze in pipelines and windshield washer fluids.
