· Hg5AsS2I3

Hg5AsS2I3 is a mixed-halide semiconductor compound containing mercury, arsenic, sulfur, and iodine—a member of the quaternary chalcohalide family. This is a research-phase material being investigated for its electronic and optical properties, particularly in contexts where tunable bandgaps and photosensitive behavior are desired; it remains largely experimental rather than established in volume production.

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.
