Used in infrared spectroscopy as a common matrix material for sample preparation, especially in the form of pressed pellets to analyze solid samples. Its transparency in the infrared region allows clear detection of absorption bands. Also historically used as an anticonvulsant and sedative in veterinary medicine, particularly for treating epilepsy in dogs. In some cases, it serves as a source of bromide ions in chemical synthesis and analytical reagents. Additionally, utilized in the production of other bromide compounds and in certain types of photographic emulsions.
