CuBr2
metal· CuBr2
Copper(II) bromide (CuBr₂) is an inorganic halide compound consisting of copper in the +2 oxidation state bonded with bromine, forming a crystalline solid with moderate mechanical stiffness. It is primarily used in organic synthesis as a catalyst and reagent in pharmaceutical and fine chemical manufacturing, as well as in analytical chemistry applications and some specialized electrochemistry contexts. Engineers and chemists select CuBr₂ over alternative copper halides when bromine's reactivity profile or specific coordination chemistry is advantageous for a particular synthetic pathway, though its corrosive nature and moderate cost-to-performance ratio limit it to specialty rather than commodity applications.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
