Cobalt Chloride Hexahydrate, identified by its CAS number 7791-13-1, is an inorganic compound of significant industrial and research value. As a leading manufacturer and supplier based in China, we understand the critical role this chemical plays across various sectors. This article delves into its fundamental properties and highlights its widespread applications, aiming to guide procurement managers and R&D scientists in their sourcing decisions.

Understanding Cobalt Chloride Hexahydrate's Properties

The most striking characteristic of Cobalt Chloride Hexahydrate is its physical appearance: a deep purple, crystalline solid. This distinct color is a result of its hydrated form, CoCl₂•6H₂O. Its melting point is around 87°C, and it possesses a density of approximately 1.924 g/cm³ at 20°C. Crucially, it is highly soluble in water, readily dissolving to form solutions of cobalt(II) ions, and also shows solubility in organic solvents like acetone and alcohols. This solubility profile makes it adaptable for use in various liquid formulations and synthesis processes. When you buy Cobalt Chloride Hexahydrate, you are acquiring a compound known for its chemical stability under appropriate storage conditions, typically in a cool, dry place, as it is hygroscopic.

Key Industrial Applications You Need to Know

The versatility of Cobalt Chloride Hexahydrate is evident in its numerous applications:

  1. Water Indicators in Desiccants: Perhaps its most recognized use is as an indicator in desiccants. When silica gel or other drying agents become saturated with moisture, the blue anhydrous form of cobalt(II) chloride changes to the pink hydrated form, visually signaling that the desiccant needs regeneration or replacement. This is a vital application for maintaining dryness in sensitive equipment and packaging.
  2. Organic Synthesis: In the realm of organic chemistry, Cobalt Chloride Hexahydrate serves as a catalyst or reagent in various synthetic pathways. Its catalytic activity can promote specific reactions, making it valuable for fine chemical manufacturers producing complex molecules. Researchers often buy Cobalt Chloride Hexahydrate for experimental synthesis work.
  3. Electroplating: The compound is employed in electroplating baths to deposit cobalt coatings onto surfaces. These coatings offer improved hardness, corrosion resistance, and aesthetic appeal to various metal parts.
  4. Diagnostic Reagents and Pharmaceutical Applications: Cobalt Chloride Hexahydrate has found applications as a stabilizer in certain radiopharmaceutical preparations, such as technetium-99m exametazime. It is also used in research to study cellular processes like apoptosis and heat shock protein expression, contributing to advancements in biomedical science.
