· Cr2 Br2 O2

Cr₂Br₂O₂ is an experimental semiconductor compound containing chromium, bromine, and oxygen. This mixed-halide oxide belongs to an emerging class of materials being investigated for optoelectronic and photocatalytic applications, where the combination of transition metal and halide chemistry offers tunable band gaps and light absorption properties. While not yet commercialized at scale, materials in this family are of research interest for next-generation solar cells, photodetectors, and catalytic devices where conventional semiconductors face limitations in cost or performance.

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.
