· Cu1 Br1 O2

Copper bromine oxide (CuBrO₂) is a ternary semiconductor compound combining copper, bromine, and oxygen elements. This material belongs to the family of mixed-halide metal oxides and is primarily of research interest for optoelectronic and photocatalytic applications, with potential in next-generation devices where copper-based semiconductors offer advantages in earth-abundance and tunability. Its notable appeal lies in the possibility of engineering bandgap and electronic properties through composition control—a key advantage over conventional semiconductors—though industrial-scale adoption remains limited and applications are largely experimental.

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.
