Product Overview
Cobalt(II) bromide UltraDry™ is a high-purity, moisture-sensitive inorganic compound designed for applications requiring ultra-low water content and minimal trace metal impurities. This 99.99% pure grade (metals basis) ensures exceptional consistency in sensitive chemical reactions, particularly those involving anhydrous conditions or transition metal catalysis. The UltraDry™ designation indicates rigorous moisture control during packaging, with each batch sealed under inert atmosphere to prevent hydration or oxidation. The compound’s deep blue crystalline form provides visual confirmation of its cobalt(II) oxidation state, while its high solubility in polar solvents makes it versatile for solution-phase applications. Unlike standard cobalt bromide, this grade undergoes additional purification to remove residual halides and other metallic contaminants, making it suitable for advanced materials research and electrochemical systems. The 5g and 1g pack sizes offer flexibility for both small-scale experiments and larger synthesis projects, with each container labeled for traceability and lot-specific certification.
FAQs
1. What is the difference between UltraDry™ and standard cobalt(II) bromide?
The UltraDry™ grade undergoes additional drying and purification steps to achieve <0.005% moisture content and 99.99% metals purity, whereas standard grades may contain higher water levels and trace impurities.
2. Can this product be used directly in air-sensitive reactions?
While packaged under inert conditions, exposure to ambient air during handling may introduce moisture. For air-sensitive applications, transfer under argon or nitrogen in a glovebox.
3. What solvents is this cobalt(II) bromide soluble in?
It is highly soluble in water, ethanol, methanol, and acetone, with moderate solubility in DMSO and DMF. Avoid nonpolar solvents like hexane.
4. How should I store unused portions to maintain purity?
Reseal the original container immediately after use, store at room temperature in a desiccator, and avoid prolonged exposure to light or humidity.
5. Is this product compatible with standard glassware?
Yes, but for long-term storage or reactions, use borosilicate glass or PTFE-lined containers to prevent potential leaching of silica or alkali metals.
