Certificado ISO 9001:2015 e ISO 14001:2015 · Suministro a laboratorios e industria desde el año 2000 · Certificado de Análisis (CoA) con cada lote
Cesium carbonate (Cs2CO3) is an inorganic salt widely used as a strong base in organic synthesis, particularly in palladium-catalyzed coupling reactions like Suzuki reactions, and as a superbase in deprotonation chemistry. It is also employed in the production of specialty glasses and as a flux in metallurgy. Cesium carbonate (CAS 534-17-8) has a minimum purity of 99.9%, a molecular weight of 325.82 g/mol, and requires ambient storage. It carries a **Danger** signal word due to its corrosive and hazardous properties. Molekula supplies cesium carbonate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
