CAS 7553-56-2

Iodine

Description:

Iodine, with the CAS number 7553-56-2, is a chemical element classified as a halogen in Group 17 of the periodic table. It is represented by the symbol "I" and is known for its distinctive dark purple-black color in its solid form, which sublimates to form violet vapors. Iodine is relatively less reactive compared to other halogens, such as fluorine and chlorine, but it can form compounds with various elements, including metals and nonmetals. It is essential for human health, particularly in the synthesis of thyroid hormones, and is commonly used as a disinfectant and antiseptic due to its antimicrobial properties. Iodine is sparingly soluble in water but dissolves well in organic solvents like alcohol and chloroform. Its molecular structure consists of diatomic molecules (I2), and it exhibits both covalent and ionic bonding characteristics in its compounds. Iodine's unique properties make it valuable in various applications, including pharmaceuticals, photography, and as a catalyst in chemical reactions.
