Product Overview
Gold(III) bromide from the Premion line delivers ultra-high purity (99.99% metals basis) with a guaranteed minimum 44.6% gold content, making it a critical reagent for applications where trace impurities cannot be tolerated. This crystalline solid is synthesized under stringent conditions to eliminate contaminant metals, halides, and non-metallic residues that could interfere with sensitive reactions or analytical measurements. The compound’s hygroscopic nature demands careful handling under inert atmospheres, while its strong Lewis acidity enables unique reactivity in organic synthesis, particularly for halogenation, cyclization, or gold-catalyzed transformations. Unlike lower-grade alternatives, Premion-grade Gold(III) bromide undergoes rigorous ICP-OES and ICP-MS testing to certify its ultra-low impurity profile, ensuring reproducibility in research-scale experiments. Its high gold content also optimizes cost efficiency for applications where gold acts as a catalyst or precursor. Store under desiccated conditions in airtight containers to prevent hydrolysis and decomposition.
FAQs
1. What is the difference between Premion-grade and standard Gold(III) bromide?
Premion-grade Gold(III) bromide undergoes additional purification steps to achieve 99.99% metals basis purity, with certified limits for individual trace metals (e.g., Pt, Pd, Fe <10 ppm). Standard grades typically range from 98-99% purity and may contain higher levels of residual halides or transition metals, which can affect catalytic performance or analytical accuracy.
2. Can this compound be used directly in aqueous solutions without further purification?
While the Premion grade minimizes impurities, Gold(III) bromide hydrolyzes rapidly in water to form hydroxo or oxo species, which may precipitate. For aqueous applications, dissolve in minimal acidic media (e.g., HBr or HCl) under inert conditions to stabilize the Au(III) species, or use freshly prepared solutions to avoid decomposition.
3. What are the key incompatibilities to avoid during storage or handling?
Avoid exposure to moisture, strong reducing agents (e.g., hydrazines, alkali metals), or basic conditions, as these trigger violent decomposition or gold reduction. Store away from ammonia, amines, or sulfur-containing compounds, which can form explosive or unstable adducts. Use glass or PTFE containers; avoid metal spatulas to prevent contamination.
4. How does the gold content (44.6% min) impact experimental yields?
The 44.6% minimum gold content ensures consistent stoichiometry in reactions where gold acts as a catalyst or reagent. Lower-purity grades with variable Au content (e.g., 40-43%) may require adjustment of reagent quantities, leading to irreproducible results. This specification is particularly critical for scaling reactions or when gold is the limiting reagent.
5. Is this product suitable for semiconductor or thin-film deposition applications?
Yes, the high purity and controlled halogen content make it suitable for CVD or ALD precursors in electronics research. However, residual bromide levels (while minimized in Premion grade) may require additional purification steps for ultra-sensitive applications like quantum dot synthesis or high-k dielectric layers. Consult process-specific impurity thresholds before use.
