Basic information
Potassium Hexacyanocobaltate(III) (CAS: 13963-58-1, Chemical Formula: K₃[Co(CN)₆]) is a highly stable, octahedral transition metal inorganic coordination complex. Unlike generic organic building blocks, this compound features a robust low-spin d6[Co(CN)6]3- coordination sphere that delivers superior thermal stability, redox inertness, and precise structural architecture.
It serves as a critical inorganic reagent for catalyst synthesis, the fabrication of functional Prussian Blue Analogues (PBAs), heterogeneous multi-metallic catalysts, and electrochemical mediators. Joy Biotech provides laboratory-to-pilot scale supply with tightly controlled trace heavy metal profiles and batch-to-batch consistency.
