Used as a solvent in industrial and laboratory applications where a polar, water-miscible medium is needed. Commonly applied in cleaning agents, surface treatments, and as a carrier in formulations for coatings and inks. Frequently used in fuel applications, such as in methanol-water injection systems for internal combustion engines to reduce engine knock and lower operating temperatures. Also utilized in some antifreeze formulations due to its freezing point depression properties when mixed with water. Plays a role in chemical synthesis as a reaction medium, especially in processes requiring controlled polarity. Widely employed in analytical techniques like HPLC and spectrophotometry as a mobile phase component or sample diluent.
