· JVASP-155367· CoCu2HgS4

CoCu2HgS4 is a quaternary sulfide compound combining cobalt, copper, mercury, and sulfur. This is a research-phase material rather than an established engineering alloy; it belongs to the family of metal sulfides and chalcogenides that are of interest for semiconductor, photovoltaic, and solid-state physics applications. The presence of mercury and multiple transition metals suggests potential for studying electronic properties, magnetic behavior, or photocatalytic performance—areas where such mixed-metal sulfides show promise compared to single-component 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.
