Product Overview
Iridium(IV) bromide, offered in Premion grade with 99.99% purity (metals basis), is a high-performance inorganic compound featuring a minimum 37.1% iridium content. This crystalline solid is engineered for demanding applications where trace impurities can compromise results. The compound’s exceptional purity ensures reliability in advanced chemical synthesis, particularly in reactions requiring a stable iridium source. Its well-defined stoichiometry and low moisture sensitivity make it suitable for use in controlled environments, including glove boxes or inert atmospheres. The Premion certification guarantees rigorous quality control, with batch-to-batch consistency verified through ICP-OES and XRD analysis. Packaged in airtight, chemically resistant containers, this product minimizes exposure to atmospheric contaminants, preserving its reactivity. Whether used as a catalyst precursor or in the preparation of iridium-based complexes, its high assay and minimal metallic impurities (typically <10 ppm) reduce the need for additional purification steps, saving time and resources in critical workflows.
FAQs
1. What is the difference between Premion and standard-grade iridium(IV) bromide?
Premion grade ensures 99.99% purity with stricter controls on trace metal impurities, while standard grades may contain higher levels of contaminants like platinum or palladium, affecting reaction outcomes.
2. Can this compound be used directly in aqueous solutions?
Iridium(IV) bromide is hygroscopic and hydrolyzes in water, forming oxybromide species. For aqueous applications, pre-dissolution in non-aqueous solvents like acetonitrile or DMSO is recommended.
3. How should unused material be stored to prevent degradation?
Store in the original sealed container under argon or nitrogen, away from light and moisture. A desiccator with a humidity indicator is ideal for long-term storage.
4. Is this product compatible with standard Schlenk line techniques?
Yes, but ensure all glassware is thoroughly dried and purged with inert gas prior to use, as the compound is sensitive to oxygen and moisture.
5. What analytical techniques confirm the 37.1% minimum iridium content?
The iridium assay is verified via inductively coupled plasma optical emission spectrometry (ICP-OES), with cross-validation using gravimetric analysis after precipitation as iridium metal.
