2-Bromopropane, also known as isopropyl bromide is the halogenated hydrocarbon with the formula CH3CHBrCH3. It is a colorless liquid. It is used for introducing the isopropyl functional group in organic synthesis.
[edit] Reactions
The bromine atom is at the secondary position, which allows the molecule to undergo dehydrohalogenation easily to give propene, which escapes as a gas. Consequently, this reagent is used in conjunction with mild bases such as potassium carbonate, vs strong ones.
[edit] Safety
Alkylating agents are often carcinogenic.
