· JVASP-27287· Nb2Se9

Nb₂Se₉ is a layered niobium selenide compound belonging to the transition metal chalcogenide family, characterized by a layered crystal structure similar to other metal dichalcogenides. This material is primarily of research interest rather than established industrial use, with potential applications in two-dimensional materials science, semiconductor devices, and catalysis, particularly where its layered structure and electronic properties could enable thin-film devices or electrochemical applications analogous to other TMD materials like MoS₂.

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.
