Cesium Carbonate CAS 534-17-8

Technical Data (Physicochemical Properties)

Applications

• Organic Synthesis Catalysis: Highly effective base for facilitating transition-metal-catalyzed cross-coupling reactions (e.g., Suzuki, Heck, and Sonogashira couplings) in the production of complex pharmaceutical intermediates.
• Optoelectronics (OLEDs): Applied as an electron injection layer material or dopant in organic light-emitting diodes to lower the operational voltage and improve overall device efficiency.
• Energy Technologies: Utilized in the development and modification of perovskite solar cells and advanced fuel cell solid electrolytes.
• Specialty Glass: Serves as a critical additive in the manufacturing of special optical glasses and fiber optics to alter the refractive index and improve transmission stability.

Storage & Safety

• Storage: Cesium carbonate is extremely hygroscopic. It must be stored in a tightly sealed, moisture-free environment. For prolonged storage of opened containers, maintaining an inert atmosphere (nitrogen or argon) is highly recommended to prevent deliquescence and carbonate conversion. Keep away from strong acids and oxidizing agents.
• Handling: Perform material transfer in a dry room or glovebox if ultra-low moisture limits must be maintained for sensitive catalytic applications. Avoid generating dust and prevent prolonged exposure to ambient humidity.
• PPE Recommendations: Operators must wear chemical-safety goggles, nitrile or neoprene gloves, and a NIOSH-approved particulate respirator to avoid respiratory irritation and skin contact during bulk handling.

Quality Assurance

Our production protocol emphasizes rigorous purification techniques to separate cesium from naturally co-occurring rubidium and potassium isotopes, ensuring a baseline purity of 99.9% or higher. Each manufactured lot undergoes strict analytical profiling using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to precisely quantify trace alkali metal impurities down to parts-per-million levels. Recognizing the chemical’s extreme sensitivity to atmospheric moisture, we implement climate-controlled packaging environments and vacuum-seal technology to guarantee that the material retains its free-flowing morphology and catalytic efficacy from the factory floor to your reactor.
