· Mo2 Se2 S2

Mo2Se2S2 is a mixed-anion layered transition metal dichalcogenide semiconductor combining molybdenum with both selenium and sulfur. This is a research-phase material being investigated for its tunable electronic and optical properties through compositional engineering of the chalcogenide ratio. It belongs to the broader family of 2D semiconductors used to explore band gap engineering and heterostructure formation beyond conventional single-chalcogenide materials like MoS2 and MoSe2.

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.
