Core application areas
1. Pharmaceutical synthesis
Antiepileptic/sedative raw materials: synthetic barbiturates (such as
phenobarbital)

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)
