Product Overview
Gadolinium(III) chloride (GdCl₃) in its anhydrous form is a high-purity, white crystalline powder with a minimum assay of 99.9% on a trace metal basis, ensuring exceptional consistency for demanding laboratory applications. This reagent is meticulously processed to eliminate residual moisture and metallic impurities, making it ideal for applications where precision and reproducibility are critical. Its high solubility in polar solvents like water and alcohols facilitates seamless integration into synthesis protocols, while its paramagnetic properties are leveraged in specialized spectroscopic techniques. The anhydrous nature of this compound prevents hydration-induced variability, ensuring reliable performance in catalytic reactions, material doping, and as a precursor for gadolinium-based complexes. Stored under inert conditions, it maintains long-term stability without degradation. Whether used as a Lewis acid catalyst, a doping agent in semiconductor research, or a calibration standard, this grade of gadolinium(III) chloride delivers uncompromised purity and batch-to-batch uniformity, reducing experimental errors and enhancing research outcomes.
FAQs
1. What is the difference between anhydrous and hydrated gadolinium(III) chloride?
Anhydrous gadolinium(III) chloride contains no water molecules in its crystal lattice, unlike the hydrated form (typically GdCl₃·6H₂O), which includes bound water. The anhydrous version offers higher purity for moisture-sensitive reactions and avoids interference in applications like spectroscopy or catalysis where water content could alter results.
2. Can this compound be used directly in aqueous solutions?
Yes, gadolinium(III) chloride anhydrous dissolves readily in water, forming a clear solution. However, it is hygroscopic and should be handled in a dry environment to prevent premature moisture absorption before use. For critical applications, freshly prepared solutions are recommended to avoid potential hydrolysis over time.
3. What precautions should be taken during storage to maintain its purity?
Store the compound in a tightly sealed container under an inert atmosphere (e.g., nitrogen or argon) to prevent exposure to moisture and air. Keep it in a cool, dry place away from oxidizing agents. Desiccants in the storage container can further extend shelf life by minimizing humidity.
4. Is this grade suitable for MRI contrast agent research?
While gadolinium(III) chloride is a precursor for some MRI contrast agents, this anhydrous, trace-metal-grade product is primarily optimized for lab-scale synthesis and analytical applications. For clinical or in vivo research, additional purification or formulation steps may be required to meet biomedical standards.
5. What alternatives exist if I need a gadolinium source with lower chlorine content?
Gadolinium nitrate or gadolinium acetate can serve as chlorine-free alternatives, though their solubility and reactivity profiles differ. For specific applications like materials science, gadolinium oxide (Gd₂O₃) is another option, though it requires additional processing to convert into soluble forms.
