Product Overview
Gadolinium(III) iodide, UltraDry™, at 99.99% purity (REO) is a high-grade rare earth compound designed for demanding laboratory applications where moisture sensitivity and trace impurities are critical concerns. This UltraDry™ variant undergoes rigorous purification and packaging under inert conditions to eliminate residual moisture, ensuring long-term stability and consistent performance in sensitive experiments. The compound’s high rare earth oxide (REO) content guarantees minimal metallic and non-metallic contaminants, making it ideal for applications requiring precise stoichiometry and reproducibility. Its crystalline or powdered form allows for easy handling and dissolution in compatible solvents, while the 99.99% purity level meets the stringent requirements of advanced material synthesis, catalysis, and optical research. The product is supplied in airtight, moisture-resistant packaging to preserve its integrity during storage and transportation, reducing the risk of hydrolysis or degradation over time.
FAQs
1. What is the significance of the UltraDry™ label in this product?
The UltraDry™ label indicates that the Gadolinium(III) iodide has been processed and packaged under ultra-low moisture conditions, typically in a glove box or dry inert atmosphere, to prevent hydration or oxidation. This ensures the compound remains in its anhydrous form, which is critical for applications where even trace moisture can alter reaction outcomes or material properties.
2. Can this compound be used directly in aqueous solutions?
Gadolinium(III) iodide is highly hygroscopic and will react vigorously with water, forming hydrated species or hydrolyzing. For aqueous applications, it must first be dissolved in a compatible non-aqueous solvent or handled under strictly anhydrous conditions to avoid unintended reactions or precipitation.
3. What are the recommended storage conditions to maintain its purity?
Store the product in its original, tightly sealed container under an inert atmosphere (e.g., argon or nitrogen) at room temperature. Avoid exposure to air or humidity, as this can compromise the UltraDry™ properties. For long-term storage, consider using a desiccator with a high-efficiency drying agent like molecular sieves or phosphorus pentoxide.
4. Is this product compatible with standard glassware, or are special materials required?
While standard borosilicate glassware is generally compatible, it is advisable to use dry, clean glassware that has been pre-treated to remove adsorbed moisture. For highly sensitive applications, consider using PTFE or other inert materials to minimize potential leaching or surface reactions, especially if the compound will be heated or stored for extended periods.
5. How does the 99.99% (REO) purity compare to lower-grade alternatives?
The 99.99% REO purity indicates that the gadolinium content is exceptionally high, with minimal impurities from other rare earth elements or metallic contaminants. Lower-grade alternatives (e.g., 99.9% or 99%) may contain higher levels of trace elements like europium, terbium, or non-rare earth metals, which can interfere with spectroscopic, catalytic, or material synthesis applications where precise composition is critical.
