· JVASP-28644· MoWSe3S

MoWSe3S is a mixed transition metal chalcogenide compound combining molybdenum, tungsten, selenium, and sulfur in a layered crystal structure. This material belongs to the family of transitional metal dichalcogenides and related compounds, representing an emerging research material rather than an established industrial product. The quaternary composition offers tunable electronic and optoelectronic properties by varying the ratio of constituent elements, making it of interest in nanoelectronics, catalysis, and energy storage research where engineers seek alternatives to single-element dichalcogenides with enhanced or engineered band gaps and surface reactivity.

Export 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.
