Used as a solvent in industrial and laboratory applications where a polar, water-miscible medium is required. Commonly applied 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. Employed in the formulation of cleaning agents, antifreeze mixtures, and fuel system cleaners because of its ability to lower freezing points and dissolve impurities. Also serves as a reagent or reaction medium in chemical synthesis, especially in esterification, transesterification, and extraction processes. Its use in aqueous form allows for controlled reactivity and improved safety compared to anhydrous methanol.
