It is used as a solvent for organic reactions extractions and Grignard reagents historically as an anesthetic (now rare) and in organic synthesis or starting fluid for engines. Additional roles include laboratory use and peroxide formation for initiators.

Its primary purpose derives from low polarity volatility for easy recovery and ability to solvate diverse compounds though peroxide instability requires stabilizers it enables hydrogen bonding as a solvent.

Ethyl Ether (Diethyl Ether) is a highly volatile colorless liquid with a characteristic ether-like odor. It is a widely used organic solvent in laboratories and industry due to its excellent solubility for many organic compounds.
