· Sr4 Fe2 S2 O6

Sr4Fe2S2O6 is an oxide-sulfide mixed-anion semiconductor compound combining strontium, iron, sulfur, and oxygen in a layered perovskite-related structure. This is a research-stage material being investigated for photocatalytic and thermoelectric applications, particularly in contexts where iron-based semiconductors with tunable bandgaps are needed to replace scarce elements or improve device performance. The dual presence of oxide and sulfide anions creates distinctive electronic properties that make it a candidate for next-generation energy conversion and environmental remediation technologies, though industrial deployment remains limited.

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.
