Used primarily as a fuel additive to enhance octane ratings in gasoline, improving engine performance and reducing knocking. It is also employed as a solvent in various chemical reactions and industrial processes due to its ability to dissolve a wide range of organic compounds. In laboratories, it serves as an extraction solvent for separating and purifying substances. Additionally, it is utilized in the production of other chemicals and as a reagent in organic synthesis. Its low miscibility with water makes it suitable for use in liquid-liquid extraction processes.
