· Mo1 W2 Se4 S2

Mo1W2Se4S2 is a mixed-metal dichalcogenide semiconductor compound combining molybdenum and tungsten with selenium and sulfur anions. This material belongs to the family of transition metal dichalcogenides (TMDCs), which are primarily explored in research and emerging device applications rather than established high-volume industrial production. The combination of two transition metals with mixed chalcogenide components makes this a complex heterostructured compound with potential for tunable electronic and optoelectronic properties compared to single-element dichalcogenides.

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.
