Ether is used as a mild anesthetic and as a solvent in industries. It is an organic compound that has sweet smell. Ether is colorless and evaporates very quickly when exposed to air. It catches fire very easily and needs to be handled with care.
In extreme cold weather, ether is used to help start a diesel or petrol engine, as it is volatile and flammable. It is also used as a refrigerant. It is used as an antiseptic to prevent infection when an injection is administered. Cotton is dipped in ether and the skin is disinfected before an injection is allowed to pierce the skin.
