Description
Potassium bromide (KBr, CAS 7758-02-3) is an inorganic bromine salt supplied as white crystalline granules or powder. Also referenced as Kalii Bromidum and NSC 77367, it carries no E-code designation and is classified under HS code 28275100 within the salts and minerals category.
In pharmaceutical manufacturing, KBr serves as a buffering agent and active sedative-anticonvulsant compound, regulating ionic balance in formulations through controlled bromide ion release. In plastics and polymer processing, it functions as a flame retardant by interrupting radical chain reactions during combustion. It also acts as a catalyst and antimicrobial additive in printing and packaging applications.
Potassium bromide is available in technical, pharmaceutical (Ph.Eur., BP), and feed-grade specifications to meet requirements across regulated industries. It is fully registered under REACH and can be supplied in multi-layer bags, fiber drums, or bulk formats depending on volume. Prospective buyers should confirm grade suitability against their applicable regulatory framework.
