Used as a solvent in industrial and laboratory applications where a polar, water-miscible medium is required. Commonly employed in analytical techniques such as high-performance liquid chromatography (HPLC) due to its compatibility with UV detection and ability to dissolve a wide range of organic compounds. Frequently used in cleaning agents for electronic components because it effectively removes oils and residues without leaving behind conductive byproducts. Applied as a fuel additive or antifreeze in windshield washer fluids, leveraging its low freezing point and solvency. Also utilized in chemical synthesis as a reaction medium, especially in processes involving acid-catalyzed reactions or extractions. Its use in fuel cells involves reforming to produce hydrogen, with aqueous methanol offering safer handling compared to pure methanol.
