Diethyl ether is a highly volatile organic solvent widely used as a reaction medium in synthesis, a solvent for extractions, and historically as an anesthetic. It is also employed in laboratories for recrystallization and as a propellant in aerosols. This clear, colorless liquid has the CAS number 60-29-7, with the molecular formula (CH3CH2)2O and a molecular weight of 74.12 g/mol. It must be stored in a tightly sealed container at ambient temperatures and handled with care, as it carries a "Danger" signal word due to its high flammability and potential to form explosive peroxides. Molekula supplies Diethyl ether from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
