Key physical and chemical properties

Core application areas

1. Pharmaceutical synthesis

• Antiepileptic/sedative raw materials: synthetic barbiturates (such as )
• 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)

Packaging and storage and transportation specifications

Storage conditions

• Environmental requirements: cool and dry warehouse, relative humidity ≤40%
• Stacking limit: pallet stacking ≤3 layers to prevent packaging damage
• Contraindications: keep away from strong acids and strong oxidants (such as nitric acid, potassium permanganate)
• Shelf life: 24 months in a sealed state

Safety and operating specifications

• Health hazards:

1. Excessive inhalation of dust can cause respiratory irritation (N95 masks are required for operation)
2. High concentration solutions contact the skin and cause burns (wear PVC gloves)

• Emergency treatment for leaks:

1. Use a plastic shovel to collect solids and place them in a closed container
2. Flush the contaminated area with large amounts of water to the wastewater treatment system

Customized services

• Particle size customization:

1. Coarse particles (1-3mm, anti-caking type for oil fields)
2. Ultrafine powder (200 mesh, accelerated pharmaceutical synthesis reaction)
