Description

Cesiumcarbonate CAS NO 534-17-7 is a highly reactive inorganic salt of cesium, a rare alkali metal. This compound is valued for its exceptional basicity and solubility in organic solvents, making it a superior catalyst and reagent compared to other carbonates. It is essential for manufacturers and researchers in the electronics, pharmaceutical, and specialty chemical industries seeking high-performance materials for advanced synthesis and material science applications.

Application

• Catalyst in Organic Synthesis: Widely used as a strong, non-nucleophilic base in C-C bond formation reactions, such as Suzuki, Heck, and aldol condensations.
• Electrolyte & Optical Material Production: A key precursor in the manufacture of specialty glasses, scintillation crystals, and electrolytes for fuel cells and high-density batteries.
• Pharmaceutical Intermediate: Employed in the synthesis of complex drug molecules, particularly where mild yet potent basic conditions are required.
• Deposition Precursor: Used in chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes to create thin films for semiconductor and optical coatings.
• Carbon Dioxide Absorption: Investigated for use in carbon capture technologies due to its high reactivity with CO₂.
• Specialty Catalyst Systems: Serves as a promoter or co-catalyst in polymerization and hydrogenation reactions.
