Used primarily as a solvent in organic synthesis and industrial applications due to its ability to dissolve a wide range of organic compounds. It is also employed as an extraction solvent in pharmaceutical and chemical processes where a moderately polar, water-immiscible ether is required. Its relatively low reactivity and good volatility make it suitable for use in reaction media and purification steps. Additionally, it serves as a reference or additive in fuel research for evaluating octane performance, though it is less common than other ethers in commercial gasoline. Safety considerations limit its large-scale use due to flammability and potential peroxide formation.
