CAS 1306-38-3 — Oxyde de cérium(IV)

Cerium (IV) oxide is a stable, white-to-yellowish powder composed of cerium in its +4 oxidation state, widely used as a polishing agent, catalyst in chemical reactions, and in gas sensors for oxygen detection. It also serves as a UV absorber in glass manufacturing and as a pigment in ceramics. This high-purity compound has a CAS number of 1306-38-3, a molecular formula of CeO₂, and a molecular weight of 172.11 g/mol. It is non-hazardous under normal conditions, requiring only ambient storage, though it carries a signal word of "Warning" for potential skin or eye irritation. Molekula supplies Cerium (IV) oxide from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
