· JVASP-141197· Cu2AgPS4

Cu2AgPS4 is a quaternary metal sulfide compound combining copper, silver, and phosphorus in a fixed stoichiometric ratio. This material belongs to the family of metal phosphide-sulfides and is primarily investigated in materials research rather than established industrial production; such compounds are of interest for their potential in solid-state ion conductivity, photovoltaic applications, and semiconductor device development due to the mixed-metal composition and sulfide chemistry.

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.
