FAQ

What is Iodine (CAS: 12190-71-5)?

Iodine is a chemical element with the symbol I and atomic number 53. It is a solid (at room temperature) non-metal and a halogen. Iodine is essential for the production of thyroid hormones. Its chemical formula is I₂. Iodine has a dark violet color and is a strong oxidizing agent.

What are the main uses of Iodine (CAS: 12190-71-5)?

Iodine is widely used in pharmaceuticals for its role in thyroid hormone synthesis. It is also used in the production of antiseptics, analytical reagents, and in the textile industry for water and flame resistance. In medicine, it is used to treat certain thyroid conditions, and in photography, it is part of the halide emulsion in X-ray films.

Is Iodine (CAS: 12190-71-5) safe?

Iodine can be toxic if ingested in large quantities. It is important to follow safety guidelines when handling iodine. Protective equipment such as gloves and goggles should be worn. Storage should be in a cool, dry place away from heat and light. Disposal of iodine should be done in accordance with local regulations to prevent environmental contamination.

How should Iodine (CAS: 12190-71-5) be stored?

Iodine should be stored in a tightly sealed container in a cool, dry place away from heat and light. It is sensitive to heat and light, and exposure to these can cause decomposition. The storage area should be well-ventilated. Do not store it with organic materials to prevent spontaneous combustion. Use appropriate containers that are resistant to iodine's effect on plastics.
