Used as a solvent in industrial and laboratory applications where a polar, water-miscible medium is needed. Commonly applied in liquid chromatography, especially in HPLC, due to its ability to dissolve a wide range of organic compounds and its compatibility with UV detection. Serves as a reagent or reaction medium in chemical synthesis, including esterification and transesterification processes, such as biodiesel production. Employed as a cleaning agent for equipment and surfaces in pharmaceutical and electronic manufacturing. Also utilized in fuel applications, such as in methanol-based fuel cells or as a component in antifreeze mixtures. Its low freezing point and high solvency make it suitable for cold-weather additives in windshield washer fluids.
