· U2 S2 O2

U2S2O2 is an experimental mixed-valence uranium oxide-sulfide compound belonging to the uranium chalcogenide family, characterized by its unique combination of uranium, sulfur, and oxygen components. This material is primarily of research interest in solid-state chemistry and materials science, with potential applications in nuclear fuel development, catalysis, and advanced ceramics where unusual oxidation state chemistry could provide beneficial properties. As a largely unstudied compound, U2S2O2 represents an exploratory material in the broader context of uranium-based functional materials, which have historically been important in nuclear technology but are now being investigated for non-nuclear applications including selective sorption and heterogeneous catalysis.

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.
