Product Overview
This UltraDry™ lithium iodide delivers exceptional 99.999% purity on a metals basis, making it ideal for applications where even trace moisture or impurities could compromise results. The anhydrous form is meticulously packaged to maintain its ultra-low water content, ensuring consistent performance in sensitive chemical reactions. Its high assay guarantees minimal metallic contaminants, which is critical for advanced inorganic synthesis and electrochemical applications. The fine crystalline structure allows for rapid dissolution in polar solvents while maintaining stability. Unlike standard grades, this material undergoes rigorous purification to eliminate halides and other ionic impurities that could interfere with catalytic processes. The product’s moisture-free packaging preserves its reactive properties during storage and handling. Researchers will appreciate its reliability in demanding protocols where reagent quality directly impacts experimental outcomes.
FAQs
1. What makes UltraDry™ lithium iodide different from standard grades?
The UltraDry™ designation indicates this product has undergone specialized drying processes to achieve moisture levels below 50 ppm, compared to standard grades that may contain 100-500 ppm water. This makes it suitable for air-sensitive chemistry where trace moisture would cause side reactions.
2. Can this be used directly in glove boxes without further drying?
While the UltraDry™ packaging maintains low moisture content, we recommend transferring to a glove box under inert atmosphere for long-term storage or highly sensitive applications, as brief exposure during opening may introduce minimal atmospheric moisture.
3. What solvents is this lithium iodide most soluble in?
The product exhibits excellent solubility in polar aprotic solvents like acetonitrile, DMSO, and DMF, as well as protic solvents including methanol and ethanol. Solubility in water is also high (143 g/100 mL at 20°C), though moisture-sensitive applications may require anhydrous conditions.
4. How should I store opened packages to maintain purity?
After opening, immediately reseal the container using the provided moisture-barrier bag and store with desiccant at room temperature. For extended storage, divide into smaller aliquots in airtight vials under argon or nitrogen atmosphere.
5. Are there any known incompatibilities with common lab materials?
Lithium iodide reacts violently with strong oxidizing agents and should not contact concentrated sulfuric acid. It may corrode some metals over time; we recommend using glass, PTFE, or polypropylene containers for storage and handling.
