· Mo3 W1 Se4 S4

Mo₃W₁Se₄S₄ is a mixed-chalcogenide layered semiconductor compound combining molybdenum, tungsten, selenium, and sulfur in a single-phase structure. This material belongs to the transition metal dichalcogenide (TMD) family and is primarily studied in research contexts for its tunable electronic and optical properties arising from the heteroatom composition. Industrial applications remain emerging, but the material shows promise in optoelectronics, catalysis, and energy storage due to the synergistic effects of multiple chalcogenide elements and the possibility of band-gap engineering through compositional control.

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.
