| Application: | Hydrobromic acid can be used as a brominating agent: • For the regioselective bromination of anilides to bromoanilides. • Oxidative bromination of olefins, alkynes, and ketones to corresponding dibrominated alkanes, dibrominated alkenes, and α-bromoketones. It can also be used as a catalyst for the aerobic photooxidation of alcohols to corresponding carboxylic acids. |
| General description: | Hydrobromic acid is a strong acid that can be used as a brominating reagent for the electrophilic and radical bromination of olefins, alkynes, and ketones. |
