Cobalt(CAS: 7440-48-4)

Cobalt is a chemical element with the CAS number 7440-48-4, atomic number 27, and symbol Co. It is a hard, lustrous, silver-gray transition metal known for its high density, magnetic properties, and resistance to corrosion. Cobalt commonly exists in +2 and +3 oxidation states and is used in various industrial and technological applications due to its unique characteristics.

Cobalt (CAS: 7440-48-4) is widely used in alloys for aerospace and electronics, batteries (e.g., lithium-ion and nickel-metal hydride), catalysts in chemical reactions, and MRI contrast agents. It also serves as a pigment in paints and ceramics, and is added to animal feed as a nutritional supplement due to its essential role in biological systems.

Cobalt (CAS: 7440-48-4) is generally safe when handled properly, but it can be toxic if inhaled, ingested, or absorbed through the skin. Safety standards, such as OSHA and EPA regulations, emphasize protective measures like gloves, ventilation, and avoiding direct contact. Long-term exposure may pose health risks, necessitating adherence to safety protocols.

Cobalt (CAS: 7440-48-4) should be stored in a cool, dry, and well-ventilated area, away from moisture, light, and incompatible materials. Use airtight containers to prevent oxidation and contamination. Ensure proper labeling and storage conditions to maintain stability and safety for extended periods.
