Used as a solvent in various industrial and laboratory applications due to its ability to dissolve a wide range of organic and inorganic substances. Commonly employed in cleaning agents and surface treatments, especially in semiconductor and pharmaceutical manufacturing where water alone is insufficient. Serves as a mobile phase in high-performance liquid chromatography (HPLC) when mixed with water, improving separation of compounds. Utilized in fuel applications, such as in methanol-water injection systems for internal combustion engines to enhance performance and reduce emissions. Also used in antifreeze formulations and as a preservative in some aqueous systems due to its antimicrobial properties.
