BROMINE ACS REAGENT >=99.5% (C005B-079024)

General description

Bromine is a highly volatile and reactive halogen that can be used as a powerful brominating and oxidizing agent in chemical synthesis.

Application

Bromine can be used as a brominating agent for the bromination of:

• Aromatic and heterocyclic compounds. 
• Carbonyl compounds at α position to carbonyl groups.
• Aromatic carboxylic acids via Hell-Volhard-Zelinski reaction in the presence of phosphorus trihalides.
• Alkylbenzenes at the benzylic position using photocatalytic conditions.

It can also be used as an oxidizing agent for the oxidation of:

• Primary alcohols to either aldehydes or esters.      
• Secondary alcohols to ketones.

It can also be used as a Lewis acid catalyst to:     

• Convert epoxides and CO₂ to cyclic carbonates in a continuous flow system.     
• Synthesize bis(indolyl)methanes by reacting indoles with carbonyl compounds.
