Cr2SeS
metal· JVASP-100017· Cr2SeS
Cr2SeS is a ternary chromium selenide sulfide compound—a mixed-anion metal chalcogenide that combines chromium with both selenium and sulfur. This is an experimental material primarily of interest to materials researchers exploring two-dimensional layered structures and electronic/photonic properties rather than an established engineering material with widespread industrial adoption. The chromium chalcogenide family is investigated for potential applications in semiconductor devices, photocatalysis, and energy storage, where the tunable bandgap and layered crystal structure could offer advantages over single-element or binary chalcogenides.

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.
