Used as a solvent in industrial and laboratory applications, especially in processes requiring a polar, water-miscible medium. Commonly applied in cleaning agents, antifreeze formulations, and as a carrier in pesticide or herbicide solutions. Also utilized in fuel applications, such as in methanol-based fuel systems or as a denaturant for ethanol. Frequently employed in analytical chemistry, including high-performance liquid chromatography (HPLC), due to its miscibility with water and suitable UV transparency. In some cases, used as a preservative or biocide in water-based systems.
