· Sb4 S4 Br4

Sb₄S₄Br₄ is an experimental mixed-halide chalcogenide semiconductor combining antimony, sulfur, and bromine in a layered crystal structure. This compound belongs to the family of chalcohalides under active research for optoelectronic and photovoltaic applications, where the inclusion of both chalcogen (S) and halide (Br) elements offers tunable bandgaps and potential advantages in light absorption and charge transport compared to single-anion semiconductors.

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.
