· Mo1 W2 Se2 S4

Mo1W2Se2S4 is a mixed-metal chalcogenide semiconductor compound combining molybdenum, tungsten, selenium, and sulfur in a layered structure. This material belongs to the family of transition-metal dichalcogenides and related mixed-metal variants, primarily of research and development interest for next-generation optoelectronic and energy-storage applications. The combination of multiple metal centers and chalcogen species offers tunable electronic properties and potential advantages in catalytic activity and charge transport compared to binary 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.
