Used primarily as a solvent in organic synthesis due to its stability and low reactivity. It is especially valuable in reactions involving strong bases or nucleophiles where more common solvents might degrade. Its volatility and boiling point make it suitable for easy removal during product isolation. Also employed as an extraction solvent in analytical chemistry and in the preparation of pharmaceuticals and fine chemicals where a non-polar, aprotic environment is needed. Additionally, it serves as an oxygenate additive in gasoline to increase the octane rating, reduce emissions, and improve cold-start performance owing to its clean combustion properties and suitable volatility.
