Product Overview
Lanthanum(III) iodide, UltraDry™ grade, delivers exceptional purity at 99.995% (metals basis), making it a critical reagent for demanding laboratory applications where trace impurities can compromise results. This anhydrous form is meticulously packaged to prevent moisture absorption, ensuring long-term stability and consistent performance in sensitive reactions. The compound’s high refractive index and optical clarity also make it valuable in specialized photonic and scintillation applications. Unlike lower-grade alternatives, this UltraDry™ variant undergoes rigorous purification to eliminate metallic and anionic contaminants, providing researchers with a reliable baseline for experimental reproducibility. Its fine crystalline structure allows for precise weighing and homogeneous dissolution in compatible solvents. Store under inert gas (argon/nitrogen) in a desiccator to maintain integrity, as exposure to ambient humidity can lead to hydrolysis and degradation of the iodide lattice. The 5g and 1g pack sizes cater to both bulk synthesis needs and small-scale high-precision experiments, minimizing waste while offering flexibility. Always handle in a glove box or dry environment to preserve its ultra-low moisture specification.
FAQs
1. What precautions should be taken when handling this Lanthanum(III) iodide?
Use a moisture-free glove box or dry nitrogen/argon atmosphere to prevent hydrolysis. Avoid exposure to air, and store sealed containers in a desiccator with a drying agent like silica gel or molecular sieves. Wear appropriate PPE, including gloves and safety goggles, as the compound is hygroscopic and can irritate skin and eyes.
2. Is this product compatible with standard organic solvents for synthesis?
It dissolves in polar aprotic solvents like acetonitrile, THF, or DMSO under anhydrous conditions. Avoid protic solvents (e.g., alcohols, water) as they can react with the iodide. Always pre-dry solvents with molecular sieves or sodium metal to eliminate residual moisture before use.
3. How does the UltraDry™ grade differ from regular Lanthanum(III) iodide?
The UltraDry™ grade guarantees ≤10 ppm residual moisture and stricter control over metallic impurities (e.g., <5 ppm for common transition metals). Regular grades may contain higher water content (up to 1-2%) and unquantified contaminants, which can interfere with sensitive applications like scintillation or catalyst preparation.
4. Can this be used as a precursor for lanthanum-based scintillator materials?
Yes, its high purity and low moisture content make it suitable for synthesizing lanthanum halide scintillators (e.g., LaI3:Ce). The absence of transition metal impurities ensures minimal quenching of luminescent centers, which is critical for achieving high light yield in radiation detection applications.
5. What is the typical shelf life under ideal storage conditions?
When stored unopened in its original packaging under inert gas at room temperature, the product remains stable for 24 months. Once opened, use within 6 months or re-seal with fresh desiccant. Degradation signs include discoloration (yellowing) or clumping due to moisture uptake.
