· KAuO2S

KAuO2S is a mixed-valence ceramic compound containing potassium, gold, oxygen, and sulfur—a relatively rare ternary/quaternary oxide-sulfide phase. This material is primarily of research interest in solid-state chemistry and materials science rather than established industrial production, with potential applications in catalysis, photocatalysis, and solid-state electronics where the unique gold coordination environment and mixed-anion framework may offer functional properties.

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.
