· O4 S1 Sr1

Sr₄O₁S₁ (strontium oxide-sulfide) is a mixed-valent ceramic compound combining strontium with both oxide and sulfide anions, representing an experimental or specialized material in the broader family of alkaline-earth chalcogenides. This material is primarily of research interest for its potential in solid-state chemistry and materials science investigations, as commercial applications remain limited; the dual anionic character may offer unique properties relevant to electrochemistry, photocatalysis, or solid electrolyte development, though industrial adoption has not yet been established.

Regulatory Screening

Environmental

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.
