| Synonyms | 3-Oxapentane, Dether, Diethyl ether, Diethyl oxide, Ether, Ethyl ether, cas 60-29-7 |
| Overview | Diethyl ether is a highly volatile, flammable organic solvent with a characteristic sweet odor. It was historically used as a general anesthetic but is now primarily used as a solvent in laboratories and industry due to its excellent ability to dissolve hydrophobic and organic compounds. Ether is also used as a starting fluid in engines due to its low ignition temperature. |
Product Information
Diethyl ether is a highly volatile, colorless liquid with a sweet odor, commonly used as a solvent in laboratories and industry. It is extremely flammable, can form explosive peroxides, and may cause dizziness or drowsiness if inhaled. Once used as an anesthetic, it is now valued for its excellent solvency in organic chemistry. Ether must be handled with care—stored away from heat and light in tightly sealed containers, and always used in well-ventilated areas or fume hoods.
