· Sr2 Cu2 S2 O2

Sr₂Cu₂S₂O₂ is an oxysulfide semiconductor compound combining strontium, copper, sulfur, and oxygen in a mixed-valent crystal structure. This material belongs to the family of layered metal chalcogenides and is primarily of research interest for photocatalytic and optoelectronic applications, where its tunable band gap and mixed anion composition offer potential advantages over single-anion semiconductors. While not yet widely commercialized, oxysulfide semiconductors like this compound are being investigated as alternatives to traditional oxides and sulfides for photocatalytic water splitting, environmental remediation, and thin-film device applications where enhanced light absorption and charge transport are desirable.

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.
