What is Zinc bromide?
Zinc bromide (CAS 7699-45-8), or ZnBr2, is an inorganic salt used as a catalyst, electrolyte component and high-density completion fluid.
Where is Zinc bromide used?
- Oil and gas: high-density clear brine fluids that control wellbore pressure without solids
- Pharmaceuticals: precursor or reagent in active ingredient synthesis needing a soluble zinc salt
- Organic synthesis and catalysis: Lewis acid catalyst for Friedel-Crafts and other electrophilic processes
- Personal care and biocides: preservation and surface-active functions in antimicrobial formulations
- It is a distinct procurement item from other zinc halides.
Commercial specifications
- Packaging from laboratory quantities to bulk industrial supply
