  • Product Details

Iodine is a chemical element with symbol I and atomic number 53. Under standard conditions, iodine is a bluish-black solid with a metallic lustre, appearing to sublimate into a noxious violet-pink gas, the color due to absorption of visible light by electronic transitions between the highest occupied and lowest unoccupied molecular orbitals. Melting point is at 113.7 °C (236.7 °F).

Iodine and its compounds are primarily used in nutrition, and industrially in the production of acetic acid and certain polymers. Iodine's relatively high atomic number, low toxicity, and ease of attachment to organic compounds have made it a part of many X-ray contrast materials in modern medicine. Iodine has only one stable isotope. Iodine radioisotopes, such as 131I, are also used in medical applications.

Disinfectants: Iodine is used as a disinfectant in various forms and can be used as disinfectants when complexes with other agents such as Povidone Iodine.
Medical application: Iodine, as an element with high electron density and atomic number, absorbs X-rays well. Potassium iodide has been used as an expectorant. Iodine also works as pharmaceutical agents in many other forms.
Analysis: Iodine is useful in analytical chemistry because of its reactions with alkenes, starch and oxidizing and reducing agents.
