CAS 7440-48-4

Cobalt

Description:

Cobalt is a transition metal with the chemical symbol Co and the CAS number 7440-48-4. It is characterized by its hard, lustrous, and silver-gray appearance. Cobalt is known for its high melting point and excellent resistance to oxidation and corrosion, making it valuable in various industrial applications. It exhibits magnetic properties and is often used in the production of high-strength alloys, batteries, and catalysts. Cobalt is also an essential trace element in biological systems, playing a critical role in the formation of vitamin B12. In terms of chemical behavior, cobalt can exist in multiple oxidation states, with +2 and +3 being the most common. It readily forms complexes with various ligands, contributing to its versatility in coordination chemistry. However, cobalt compounds can be toxic in certain forms, necessitating careful handling and regulation in industrial and laboratory settings. Overall, cobalt's unique properties make it an important element in both technological and biological contexts.
