Sodium Bromide丨CAS 7647-15-6

1. Oil and Gas Industry

Used in drilling and completion fluids as a density-adjusting brine.

Prevents well collapse, controls formation pressure, and minimizes formation damage.

Preferred in high-density and high-pressure environments.

2. Photographic Industry

Acts as a restrainer in photographic developers.

Controls the rate of development and improves image sharpness in black-and-white films.

3. Water Treatment

Forms bromine-based disinfectants (e.g., sodium hypobromite) when mixed with oxidizers like chlorine.

Used in cooling towers, spas, and swimming pools for algae and bacterial control.

Less irritating than chlorine and effective over a broader pH range.

4. Pharmaceuticals

Previously used as a sedative and anticonvulsant.

Now used in bromide salts for veterinary medicine or as a brominating agent in synthesis.

5. Chemical Synthesis

Employed in the manufacture of organic bromides, especially via nucleophilic substitution.

Useful for producing flame retardants, dyes, and agrochemicals.

6. Analytical Chemistry

Used as a source of bromide ions in titrations, ion-selective electrodes, or infrared spectroscopy (KBr disks with additives).

✅ High Solubility: Easily forms stable aqueous solutions, important for industrial and laboratory use.

✅ Safe Handling: Compared to elemental bromine, NaBr is non-volatile and easier to store and transport.

✅ Broad Utility: Serves roles in industrial processes, chemical synthesis, water treatment, and analytical applications.

✅ Stable Compound: Chemically stable under normal conditions, with a long shelf life.
