Diethyl Ether (DEE / Ether)
CAS Number: 60-29-7
Diethyl ether (DEE, ≥99.5%) is a low-boiling ether with excellent solvency for fats, oils, waxes, and many organic compounds. It is widely used as a laboratory extraction solvent, a starter fluid for diesel engines in cold conditions, an industrial cleaning agent, and a reaction medium for Grignard reagents and metal-organic chemistry.
