Bromoethane, also known as ethyl bromide, is a chemical compound of the haloalkanes group.

The preparation of EtBr stands as a model for the synthesis of bromoalkanes in general.

A laboratory synthesis includes reacting ethanol with a mixture of hydrobromic and sulfuric acids.

[4] In organic synthesis, EtBr is the synthetic equivalent of the ethyl carbocation (Et+) synthon.

[8] Short chain monohalocarbons in general are potentially dangerous alkylating agents.
