IODINE Chemical compatibility with O-rings, rubbers, & plastics

Iodine is a dark purple-black solid with a characteristic odor, used in various industrial, medical, and laboratory applications. It is an essential element for thyroid function in humans and animals. Iodine is used as a disinfectant, antiseptic, and in the production of iodine compounds. It is also employed in chemical synthesis, analytical chemistry, and as a catalyst in various reactions. Despite its benefits, iodine can be toxic if inhaled, ingested, or absorbed through the skin in large amounts. Proper handling, storage, and safety measures, including the use of personal protective equipment, are essential to minimize risks and ensure safe usage.
