Industrial Uses

1. Pharmaceuticals

  • Sedative and Anticonvulsant (Historical Use): Potassium bromide was once widely used as a central nervous system depressant to treat epilepsy and nervous disorders. It works by releasing Br⁻ ions, which have inhibitory effects on neuronal activity. Though replaced by safer alternatives, it is still used in veterinary medicine for managing canine epilepsy.
  • Excipients in Controlled-Release Tablets: KBr is sometimes used in formulations to help regulate osmotic pressure or ionic balance, influencing drug release behavior in modified-release tablets.

2. Construction

  • High-Density Brine in Drilling Fluids: Potassium bromide is used in clear brine fluids for oil and gas well completion and workover operations. It provides density and ionic balance to control well pressure and prevent blowouts.
  • Shale Inhibitor: Helps stabilize shale formations during drilling, reducing the risk of wellbore collapse or swelling in water-sensitive formations.

3. Performance Chemicals

  • Source of Bromide Ion in Synthesis: Used in halide exchange reactions, Grignard reactions, and nucleophilic substitution, where it supplies bromide ions in a stable, easily handled salt form.
  • Intermediate in Organic Compounds: KBr is used to generate other bromine-containing compounds, such as alkyl bromides or perbromates, during chemical synthesis.
  • IR Spectroscopy (FTIR Grade): Due to its optical transparency in the infrared region, potassium bromide is widely used to prepare pellets for FTIR (Fourier Transform Infrared) spectroscopy. It does not interfere with IR spectra, making it an ideal sample matrix.
  • Reagent for Bromide Testing: Used as a standard or source of bromide ions in laboratory analysis, such as quantitative titrations or precipitation reactions (e.g., with silver nitrate).

4. Animal Healthcare

  • Treatment for Canine Epilepsy: Still commonly prescribed in veterinary neurology to control seizures in dogs, especially when phenobarbital is not tolerated. It provides long-term seizure control with relatively low toxicity.
