The high solubility of cobalt nitrate makes it a common source of cobalt in metal-organic frameworks and polymers. It is also reduced to metallic cobalt or precipitated on various substrates for Fischer-Tropsch catalysis. Cobalt is a metallic element with the atomic number 27. It is found naturally in rocks, soil, water, plants, and animals. In small amounts cobalt is an essential element for life, as it is part of vitamin B12. However, excess exposure is known to exhibit toxic effects. Nitrite is a toxic compound known to cause methemoglobinemia. (L1137,  L29, L30, L492)"}]
