Used as a solvent in industrial and laboratory applications where a polar, water-miscible medium is needed. Commonly applied in analytical techniques such as high-performance liquid chromatography (HPLC) due to its UV transparency and ability to dissolve a wide range of organic compounds. Employed in the formulation of cleaning agents, antifreeze mixtures, and fuel system cleaners. Also serves as a reagent or reaction medium in chemical synthesis, including esterification and transesterification processes. Its use in water allows for controlled polarity and reduced flammability compared to pure methanol.
