Cesium Carbonate (Cs2CO3) | High Purity Organic Synthesis & Electronic Grade | CAS 534-17-8
Overview
Cesium Carbonate (Cs2CO3) is a white, crystalline powder that is highly hygroscopic and readily soluble in water, alcohol, and ether. Unlike other alkali metal carbonates, its superior solubility in organic solvents makes it an extraordinarily versatile and mild base. It has become an indispensable reagent in advanced organic synthesis and a foundational material in cutting-edge optoelectronics.
Product Description
Cesium Carbonate (Cs2CO3) | High Purity Grade
Product Overview
Cesium Carbonate (Cs2CO3) is a white, crystalline powder that is highly hygroscopic and readily soluble in organic solvents. Unlike other alkali metal carbonates, its superior solubility makes it an extraordinarily versatile and mild base. It has become an indispensable reagent in advanced organic synthesis and a foundational material in cutting-edge optoelectronics.
At Shandong Yinglang Chemical Co., Ltd., established in 2016, we supply High-Purity Cesium Carbonate (3N 99.9% and 4N 99.99%) meticulously engineered for the pharmaceutical and electronic industries. By strictly enforcing ppm-level control over other alkali metals and maintaining absolute dryness, our product guarantees exceptional catalytic yields and flawless electronic performance.
Technical Specifications (COA)
For advanced cross-coupling reactions and OLED manufacturing, trace impurity control is paramount. Typical specifications for our 3N Grade:
| Purity (Cs2CO3) | ≥ 99.9% |
|---|---|
| Rubidium (Rb) | ≤ 100 ppm |
| Potassium (K) | ≤ 50 ppm |
| Sodium (Na) | ≤ 50 ppm |
| Loss on Drying (Moisture) | ≤ 0.2% |
Key Applications
- Advanced Organic Synthesis: The premier inorganic base for transition-metal-catalyzed cross-coupling reactions (Suzuki, Buchwald-Hartwig). Dramatically increases yields in the synthesis of complex pharmaceutical APIs.
- OLEDs & Optoelectronics: Utilized as an electron injection layer (EIL) material in OLEDs and perovskite solar cells to lower the work function and enhance device efficiency.
- Specialty Glasses: Acts as a flux to lower melting temperatures and improve the refractive index of specialty optical glasses.
🔬 The Ultimate Base for Cross-Coupling
In complex pharmaceutical synthesis, replacing potassium carbonate with our High-Purity Cesium Carbonate drastically improves the solubility of the base in organic solvents (like toluene or DMF). This leads to faster reaction times, significantly higher yields, and fewer unwanted byproducts in demanding Buchwald-Hartwig aminations and Suzuki-Miyaura couplings.
Packaging Options
Because Cesium Carbonate is exceptionally deliquescent, our packaging protocol ensures absolute dryness:
- 25 KG Vacuum-sealed inside thick aluminum foil barrier bags, securely packed in Fiber Drums.
- Custom small-volume packaging (1 KG / 5 KG / 10 KG) available for CROs and R&D laboratories.
⚠️ Safety & Handling Profile
Transport: Classified as Non-Dangerous Goods (General Cargo) for ocean transport.
Handling: It is a strong irritant to the eyes, respiratory system, and skin. Operators MUST wear protective gloves, safety goggles, and dust masks. It must be handled rapidly in the open air or inside a glove box to prevent moisture absorption, which causes the powder to clump and degrade.

FAQ
Q1: What documents and certifications do you provide?
A Standard shipment includes COA (Certificate of Analysis) and MSDS (SDS). We also provide ISO 9001 certification and support third-party inspections like SGS or BV upon request.
Q2: Do you provide custom synthesis or formulation services?
A Yes. If you have specific purity requirements or a unique formulation, our R&D team can provide custom synthesis and adjust the stabilizers/inhibitors to meet your technical specifications.
Q3: What are your terms of payment?
A
For Orders ≤ $1,000: 100% in advance.
For Orders > $1,000: 30% T/T in advance, and the balance before shipment or against the copy of B/L. Irrevocable L/C at sight is also acceptable for bulk orders.
Q4: How long is your price valid?
A Chemical prices fluctuate due to the changes in raw material costs and exchange rates. Please contact our sales team for the latest real-time quotation.
Q5: What packaging and shipping ports are available?
A
We normally ship from Qingdao, Shanghai, or Ningbo.
Standard packaging includes 200kg Drums or 1000kg IBC Totes. We ensure strict safety compliance for both general and hazardous chemical cargoes.
Q6: It's my first time importing chemicals — can you help?
A Absolutely. Importing chemicals requires specific documentation. Our experienced logistics team will assist you with the entire process, including handling customs clearance documents and arranging the most suitable shipping method.
