It is a colorless liquid. It is used for introducing the isopropyl functional group in organic synthesis. 2-Bromopropane is prepared by heating isopropanol with hydrobromic acid.[3] Preparation2-Bromopropane is commercially available. It may be prepared in the ordinary manner of alkyl bromides, by reacting isopropanol with phosphorus and bromine,[4] or with phosphorus tribromide.[5] ReactionsThe 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, rather than strong ones. SafetyAlkylating agents are often carcinogenic. Further reading
