Core application areas
- Pharmaceutical synthesis
- Antiepileptic/sedative raw materials: synthetic barbiturates (such as phenobarbital)
- Contrast agent excipients: stabilizer for sodium iodide solution for CT scanning
- 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
- Photosensitive industry
- Photographic emulsions: bromide ion source for traditional film developers
- Organic synthesis
- Phase transfer catalysts: Williamson ether synthesis reaction
- Bromination reagents: preparation of brominated alkanes (such as ethyl bromide)
- Flame retardant additives
- Enhance the flame retardant properties of plastics/textiles (synergistic with antimony oxide)
