Product Name – Lanthanum(III) chloride, UltraDry™, 99.99% (metals basis) Quantity/Pack Size – 25g, 5g Form – Solid (anhydrous) Grade – UltraDry™ (99.99% metals basis) Application – Catalysis, material synthesis, optical coatings
Product Overview
Lanthanum(III) chloride, UltraDry™ grade, delivers 99.99% metals basis purity, ensuring minimal impurities for demanding laboratory applications. This anhydrous form is meticulously processed to eliminate moisture and trace contaminants, making it ideal for processes where reactivity and consistency are critical. The compound’s high solubility in polar solvents like water and ethanol facilitates seamless integration into solution-based protocols. Its hygroscopic nature requires careful handling under inert conditions to maintain stability. The UltraDry™ designation guarantees rigorous quality control, with residual moisture levels below 50 ppm, meeting the exacting standards of advanced research environments. This product is particularly valued in catalysis, where lanthanum’s Lewis acidity enhances reaction efficiency, and in material science for synthesizing high-purity ceramics and optical coatings. Packaged in airtight containers with desiccant protection, it ensures long-term shelf life without degradation. Researchers benefit from its predictable stoichiometry and batch-to-batch uniformity, reducing variability in experimental outcomes. Whether used as a precursor in nanotechnology or as a dopant in solid-state chemistry, this grade provides the reliability needed for reproducible results.
FAQs
1. What is the difference between UltraDry™ and anhydrous lanthanum chloride?
UltraDry™ refers to a proprietary purification process that ensures residual moisture levels below 50 ppm, whereas standard anhydrous grades may contain higher trace moisture. This makes UltraDry™ more stable for moisture-sensitive reactions.
2. Can this product be used in aqueous solutions without precipitation?
Lanthanum(III) chloride is highly soluble in water (up to 97 g/100 mL at 20°C), but rapid dissolution in cold water may cause localized precipitation due to hydration exotherm. Pre-warming the solvent or gradual addition is recommended.
3. What are the storage requirements to prevent hydrolysis?
Store in a desiccator under nitrogen or argon at 15–25°C. Original packaging should remain sealed until use, and exposure to ambient humidity should be minimized to avoid forming hydrated species like LaCl₃·7H₂O.
4. Is this compatible with glassware, or does it react with silica?
The compound is chemically stable with borosilicate glass under inert conditions. However, prolonged contact with moist glass surfaces may lead to etching due to the release of hydrochloric acid upon hydrolysis.
5. Are there lower-purity alternatives available for cost-sensitive applications?
Standard reagent-grade lanthanum chloride (99.9% purity) is available for less critical applications, though it may contain higher levels of alkali metal or rare earth impurities that could interfere with sensitive analyses.
