Product Overview
Lanthanum(III) chloride UltraDry™ is a high-purity, anhydrous rare-earth metal halide designed for applications demanding minimal moisture interference. With a 99.9% rare-earth oxide (REO) purity, this compound eliminates hydration-related variability, ensuring consistent performance in synthesis, catalysis, and advanced material fabrication. The UltraDry™ processing guarantees residual moisture levels below standard reagent grades, making it ideal for air-sensitive reactions where trace water can compromise yields or product integrity. Its crystalline powder form allows precise weighing and homogeneous dissolution in polar solvents like alcohols or water (with controlled hydration). The compound’s Lewis acidity and coordination versatility enable its use as a catalyst in organic transformations, while its optical properties support applications in glass doping and luminescent materials. Stored under inert conditions, this grade retains stability over prolonged periods, reducing the need for pre-treatment before use. Compatibility with glove-box or Schlenk-line techniques further enhances its utility in high-stringency environments. Unlike hydrated alternatives, this anhydrous form avoids weight discrepancies and reactivity inconsistencies, providing reproducible results across batches. Researchers benefit from its defined stoichiometry and lack of bound water, which simplifies reaction workups and purification steps.
FAQs
1. How does UltraDry™ processing differ from standard anhydrous grades?
UltraDry™ involves rigorous moisture removal under controlled atmospheric conditions, achieving residual water content below 50 ppm, whereas standard anhydrous grades may contain up to 100–200 ppm. This reduces side reactions in sensitive applications.
2. Can this be used directly in glove-box environments without further drying?
Yes, the UltraDry™ grade is packaged under argon and sealed to maintain anhydrous conditions, allowing direct use in glove boxes without additional drying steps, provided the container is opened in an inert atmosphere.
3. What solvents are compatible for dissolving this compound?
It dissolves readily in polar aprotic solvents like THF, acetonitrile, and alcohols (e.g., ethanol, methanol). Avoid protic solvents if moisture-sensitive reactions are planned, as trace water in solvents can react with the chloride.
4. Are there alternatives for applications requiring lower purity?
For less demanding applications, hydrated lanthanum chloride (e.g., LaCl₃·xH₂O, 99.5% purity) is a cost-effective alternative, though it introduces water content and may require pre-drying for anhydrous reactions.
5. What is the recommended storage protocol to maintain anhydrous conditions?
Store unopened containers in a desiccator under nitrogen or argon at room temperature. After opening, reseal immediately with parafilm and store under inert gas to prevent moisture absorption. Avoid prolonged exposure to ambient air.
