Product Overview
Bismuth(III) iodide (BiI₃) from Eqipped is an ultra-high-purity reagent (99.998% metals basis) designed for demanding laboratory applications where trace impurities can compromise results. The UltraDry™ grade ensures exceptionally low moisture content, making it ideal for air-sensitive reactions and advanced materials research. This compound exhibits a distinctive dark gray to black crystalline structure with a high melting point (408°C), providing stability under thermal stress. Its layered crystal lattice structure contributes to unique semiconductor properties, particularly in optoelectronic applications. The reagent is packaged under inert conditions to preserve its pristine quality, with each batch rigorously tested for metallic and anionic impurities. The 99.998% purity specification guarantees minimal interference in analytical procedures, while the UltraDry™ processing eliminates residual water that could catalyze unwanted side reactions. Researchers will appreciate its consistent stoichiometry and batch-to-batch reliability, which are critical for reproducible experimental outcomes in materials science and inorganic chemistry applications.
FAQs
1. What precautions should be taken when handling Bismuth(III) iodide due to its air sensitivity?
Store and handle under inert gas (argon/nitrogen) in a glove box or Schlenk line. Use oven-dried glassware and avoid exposure to ambient moisture, which can cause hydrolysis and degradation of the compound. Always reseal the container immediately after use and store with desiccant.
2. How does the UltraDry™ grade differ from standard Bismuth(III) iodide?
The UltraDry™ designation indicates additional purification steps to remove residual moisture and volatile impurities. Standard grades typically contain 1-5% water by weight, while UltraDry™ reduces this to <50 ppm, preventing hydrolysis reactions and ensuring consistent performance in moisture-sensitive applications.
3. What is the typical shelf life when stored under ideal conditions?
When stored unopened in its original packaging under inert atmosphere at room temperature, the reagent maintains its specified purity for 24 months. Once opened, use within 6 months for optimal performance, though proper resealing can extend this period.
4. Are there any known incompatibilities with common lab solvents?
Bismuth(III) iodide reacts violently with strong oxidizing agents and is incompatible with alcohols, amines, and water. It dissolves in polar aprotic solvents like DMSO and DMF but may decompose in protic solvents. Always check compatibility before mixing with other reagents.
5. What analytical techniques are recommended for verifying the compound’s purity?
Inductively coupled plasma mass spectrometry (ICP-MS) is ideal for trace metal analysis, while ion chromatography can detect anionic impurities. Powder X-ray diffraction (PXRD) confirms crystalline phase purity, and Karl Fischer titration quantifies residual moisture content below the specified threshold.
