Diethyl Ether

Diethyl Ether

Description:

Diethyl Ether (also known as ethyl ether or simply ether) is a volatile, highly flammable, and colorless organic liquid with a distinctive, sweet odor. It is a member of the ether class of compounds and has been widely used as a solvent in laboratories and industries. Historically, it was also used as a general anesthetic, although it is no longer used for that purpose due to safety concerns.
