Potassium bromide (KBr) is an inorganic salt that functions as an anticonvulsant and sedative, commonly used in veterinary medicine, particularly for epilepsy in dogs and cats. It is a white, crystalline solid that is freely soluble in water and is primarily used in combination with other anticonvulsant drugs like phenobarbital, or as a sole anticonvulsant in some cases.Potassium Bromide 99.5% AR refers to Potassium Bromide (KBr), a white crystalline powder, with a purity of at least 99.5%, designated as an Analytical Reagent (AR) grade, indicating its suitability for use in chemical analysis and research. AR grade chemicals are known for their high purity and low levels of impurities, making them reliable for precise applications.
