· Na5 Co1 S1 O2

Na₅CoSO₂ is an experimental mixed-anion compound combining sodium, cobalt, sulfur, and oxygen in a single phase—a rare composition that bridges sulfide and oxide chemistry. This material belongs to the emerging class of multianion semiconductors under investigation for solid-state ion transport and electrochemical energy storage, where the presence of multiple anionic sublattices can enable novel conduction pathways unavailable in conventional oxides or sulfides alone.

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.
