Product Name – Cobalt(II) chloride, UltraDry™, 99.9% (metals basis) Quantity/Pack Size – 25g, 5g, 1g Form – Solid (anhydrous) Grade – UltraDry™, 99.9% (metals basis) Application – Moisture-sensitive reactions, analytical chemistry
Product Overview
Cobalt(II) chloride, UltraDry™ (99.9% metals basis) is a high-purity, anhydrous inorganic compound designed for applications requiring minimal moisture interference. This grade ensures exceptional stability and reactivity, making it ideal for precise laboratory processes where trace water content could compromise results. The UltraDry™ designation guarantees rigorous moisture control during packaging, preserving the compound’s integrity until use. Its deep blue crystalline form provides visual confirmation of purity, while the 99.9% metal basis specification ensures consistent performance in analytical and synthetic workflows. The compound’s hygroscopic nature demands careful handling, but its high purity compensates by delivering reliable stoichiometry in reactions. Packaged in airtight containers, this Cobalt(II) chloride variant maintains its anhydrous state, eliminating the need for additional drying steps. Researchers benefit from its predictable behavior in coordination chemistry, redox reactions, and as a catalyst precursor. The absence of hydrate forms simplifies calculations and reduces variability in experimental outcomes.
FAQs
1. What is the difference between anhydrous and hydrated Cobalt(II) chloride?
Anhydrous Cobalt(II) chloride is free from water molecules, appearing blue, while hydrated forms (like the hexahydrate) are pink due to coordinated water. The UltraDry™ grade ensures the anhydrous form for moisture-sensitive applications.
2. Can this be used as a humidity indicator?
While Cobalt(II) chloride changes color with hydration (blue to pink), the UltraDry™ grade is optimized for lab use, not as a commercial humidity indicator. Contamination risks make it unsuitable for repeated exposure.
3. How should I store this to prevent moisture absorption?
Store in the original airtight container with desiccants in a cool, dry place. Avoid opening in humid environments; use a glove box or dry nitrogen atmosphere for long-term storage.
4. Is this compatible with glassware and standard lab solvents?
Yes, but avoid prolonged contact with strong acids or bases, which may corrode glass or react with the compound. Use PTFE-lined containers for storage if needed.
5. What alternatives exist for moisture-sensitive cobalt sources?
Cobalt(II) acetate or cobalt(II) nitrate (anhydrous grades) can substitute in some reactions, but their solubility and coordination properties differ. Consult reaction-specific literature for suitability.
