Potassium Bromide (CAS 7758-02-3) is a colorless to white crystalline halide salt, neutral in reaction and structurally similar to sodium chloride, supplied as white random crystals; it serves pharmaceutical and veterinary formulators as a sedative and anticonvulsant component, while analytical laboratories use it to prepare transparent pellets for infrared spectroscopy. When heated, it releases hydrogen bromide vapors.

Potassium Bromide
Applications
Widely used in pharmaceuticals as a sedative and anticonvulsant component in veterinary formulations. In analytical laboratories, it is essential for infrared spectroscopy, forming transparent KBr pellets for sample analysis. Industrially, it’s applied in photography, heat treatment salts, and as a corrosion inhibitor in metal processing.
Safety & Risks
Non-flammable but harmful in excessive ingestion. Inhalation of dust should be avoided. Use PPE in laboratory settings.
Packaging
Supplied in 25 kg plastic-lined paper bags or 50 kg fiber drums. Store cool, dry, and sealed away from acids or oxidizers to prevent decomposition.
