Cobalt Nitrate (CAS 10026-22-9) is a cobalt(II) salt that typically occurs as a red, deliquescent hexahydrate, and it serves as a catalyst precursor for petroleum refining, a Vitamin B12 precursor in ruminant feed, and a colorant in ceramics and glass. Its excellent solubility makes it ideal for creating specialized impregnation solutions.
In agriculture, it is used in trace amounts in animal feed to support Vitamin B12 synthesis in ruminants. Its consistent quality ensures the safe delivery of essential micronutrients in commercial livestock nutrition.
The compound is also a staple in the ceramics industry for producing deep blue pigments. Its reddish-brown crystals are highly reactive, serving as a versatile intermediate for fine chemical manufacturing.
