Cas no 932-69-4 (Cobalt(II) benzoate tetrahydrate)

Cobalt(II) benzoate tetrahydrate (Co(C?H?O?)?·4H?O) is a coordination compound consisting of cobalt(II) ions complexed with benzoate ligands and four water molecules. This purple to pink crystalline solid is sparingly soluble in water and organic solvents. It serves as a precursor in catalysis, particularly for oxidation reactions, and finds applications in materials science for synthesizing cobalt-based complexes or nanomaterials. The tetrahydrate form ensures stability and controlled reactivity in synthetic processes. Its defined stoichiometry and purity make it suitable for research and industrial use, where precise cobalt incorporation is required. Handling should follow standard safety protocols for cobalt compounds.
