· S2 Cr1 Au1

S2Cr1Au1 is an experimental semiconductor compound combining sulfur, chromium, and gold in a 2:1:1 composition ratio. This material belongs to the emerging class of mixed-metal chalcogenides, which are being investigated for optoelectronic and photovoltaic applications where conventional semiconductors face limitations. The incorporation of gold—a noble metal—alongside chromium and sulfur is notable in research contexts exploring enhanced electrical conductivity, optical properties, or catalytic behavior, though it remains largely confined to laboratory development rather than widespread industrial 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.
