Product Overview
Neodymium(III) chloride (NdCl₃) in its anhydrous form represents a high-purity rare earth metal halide, meticulously refined to 99.9% trace metal basis for demanding laboratory applications. This hygroscopic violet powder exhibits exceptional solubility in polar solvents while maintaining stability under inert conditions, making it indispensable for specialized chemical processes. The anhydrous nature eliminates water interference in reactions, ensuring consistent stoichiometry in synthesis protocols. Its trace metal certification guarantees minimal contamination from transition metals or other impurities that could compromise experimental integrity. The compound’s strong Lewis acidity and unique electronic configuration enable its use in coordination chemistry, where it forms stable complexes with organic ligands. Storage under argon or vacuum is recommended to preserve its anhydrous state, as exposure to atmospheric moisture rapidly converts it to the hydrated form. The 5-gram packaging provides an optimal balance between research-scale requirements and cost efficiency, while the powder form allows precise weighing for micro-scale applications. As a lanthanide halide, it demonstrates characteristic paramagnetic properties that can be exploited in advanced material science applications.
FAQs
1. What is the difference between anhydrous and hydrated neodymium chloride?
Anhydrous neodymium chloride contains no water molecules in its crystal structure, offering higher purity and reactivity for moisture-sensitive applications. The hydrated form typically contains 6 water molecules per formula unit, which may interfere with certain chemical reactions.
2. Can this product be used directly in aqueous solutions?
While soluble in water, the anhydrous form will initially react exothermically with water to form the hydrated version. For aqueous applications, it’s recommended to first dissolve in a minimal amount of acid or prepare fresh solutions as needed.
3. What precautions should be taken during handling?
Handle under inert atmosphere (argon/nitrogen) in a glove box or with Schlenk techniques. The compound is highly hygroscopic and can cause skin irritation. Always use appropriate PPE including gloves and safety goggles.
4. How should this be stored for long-term use?
Store in a tightly sealed container under dry argon or in a vacuum desiccator. Keep away from moisture sources and maintain at room temperature. Avoid glass containers for long-term storage as trace metals may leach.
5. What analytical techniques can verify its purity?
Inductively coupled plasma mass spectrometry (ICP-MS) is the standard method for verifying trace metal purity. X-ray diffraction can confirm the anhydrous phase, while Karl Fischer titration can detect residual moisture content.
