Description

Potassium bromide (CAS 7758-02-3 ), commonly identified by its formula abbreviation KBr, is an inorganic bromide salt used across pharmaceutical, industrial, and specialty chemical manufacturing. It functions as a source of bromide ion in synthesis and a flame retardant additive. This versatile compound also serves as a process chemical in photographic and printing applications. In pharmaceutical manufacturing, KBr serves as an intermediate in the synthesis of active ingredients and as a buffering agent in formulation development. Printing and packaging operations use it as a component in photographic emulsions and plate processing chemistry. In these applications, controlled bromide concentration governs image quality and development rates during the production cycle. Plastics and polymer producers incorporate it as a flame retardant precursor, particularly in systems requiring halogen-based fire suppression. In catalytic applications, KBr acts as a catalyst modifier or precursor in oxidation and bromination reactions. These chemical processes influence selectivity in fine chemical synthesis for various industrial sectors. Potassium bromide is supplied as a white crystalline powder or granules depending on the specific application requirements of the end user. Pharmaceutical-grade material is available to USP and BP specifications, supporting regulated manufacturing environments. This ensures compliance with international quality standards for medicinal and therapeutic product development. Technical-grade product is also offered for industrial process use where pharmacopeial certification is not required. This grade provides a cost-effective solution for large-scale manufacturing, photography, and polymer additive applications. Contact us for supply of Potassium bromide Request Quote
