· Cs2HgI2Cl2

Cs₂HgI₂Cl₂ is a mixed-halide hybrid perovskite semiconductor containing cesium, mercury, iodide, and chloride ions. This is primarily a research-phase material studied for its optoelectronic properties rather than an established industrial compound; it belongs to the halide perovskite family, which has gained attention for potential applications in radiation detection, photovoltaic devices, and scintillation detection due to the high atomic number of mercury and tunable bandgap from halide composition control. The material represents an experimental approach to developing lead-free and tin-free alternative perovskites, though stability and toxicity considerations remain critical research challenges compared to more established semiconductor alternatives.

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.
