· Cd4 Hg4 As4 Br4

Cd₄Hg₄As₄Br₄ is an experimental quaternary semiconductor compound combining cadmium, mercury, arsenic, and bromine—a complex halide-based system that falls outside conventional commercial materials. This material exists primarily in research contexts exploring novel semiconductor compositions, particularly for optoelectronic or photonic applications where multi-element systems can enable tunable bandgaps or unique electronic properties unavailable in binary or ternary compounds. The inclusion of mercury and arsenic—both toxic heavy elements—significantly constrains practical deployment, making this compound of academic interest for fundamental solid-state physics and materials discovery rather than production engineering.

Quality & Standards

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.
