Contrast agent excipients: stabilizer for sodium iodide solution for CT scanning

2. Industrial water treatment

Bactericides and algaecides: Bromine-based disinfectants for cooling towers and swimming pools (replacing chlorine and reducing the production of carcinogens)

Oilfield drilling fluids: inhibit sulfate-reducing bacteria (SRB) from corroding pipelines

3. Photosensitive industry

Photographic emulsions: bromide ion source for traditional film developers

4. Organic synthesis

Phase transfer catalysts: Williamson ether synthesis reaction

Bromination reagents: preparation of brominated alkanes (such as ethyl bromide)

5. Flame retardant additives

Enhance the flame retardant properties of plastics/textiles (synergistic with antimony oxide)
