Product Overview
This Puratronic™ cesium carbonate delivers exceptional 99.994% purity (metals basis), making it one of the highest-grade cesium carbonate reagents available for demanding laboratory applications. The ultra-low trace metal content ensures minimal interference in sensitive analytical procedures, while the consistent particle size distribution guarantees uniform reactivity. As a strong organic base, it exhibits excellent solubility in polar solvents and maintains stability under inert conditions. The product is rigorously tested for heavy metal contaminants and packaged under argon to prevent moisture absorption. Its high basicity (pKa ~10.4) and non-nucleophilic nature make it particularly valuable for deprotonation reactions where traditional bases may cause side reactions. The powder form allows for precise weighing and easy dissolution in reaction mixtures. Each batch comes with a certificate of analysis verifying the exact impurity profile.
FAQs
1. What is the difference between Puratronic™ and standard-grade cesium carbonate?
Puratronic™ grade undergoes additional purification steps to achieve 99.994% purity with significantly lower trace metal content compared to standard grades which typically range between 99.5-99.9%.
2. Can this product be used in air-sensitive reactions?
The product is packaged under argon and should be stored in an inert atmosphere. While it’s not pyrophoric, it can absorb moisture from air over time, so handling in a glove box is recommended for air-sensitive applications.
3. What is the typical moisture content of this cesium carbonate?
Our Puratronic™ cesium carbonate typically contains less than 0.05% moisture by weight, as verified by Karl Fischer titration in our quality control process.
4. How should I dispose of unused cesium carbonate?
Neutralize with dilute acid before disposal according to local regulations. The product is not RCRA hazardous but should be handled as a corrosive material due to its basic nature.
5. What is the shelf life of this product when stored properly?
When stored in its original packaging under inert atmosphere at room temperature, the product maintains its specified purity for at least 3 years from the date of manufacture.
