Used as a source of iodine in dietary supplements and iodization of table salt to prevent iodine deficiency disorders. Commonly employed in analytical chemistry for titrations, particularly in redox reactions involving iodine. Acts as an oxidizing agent in various laboratory and industrial processes. Utilized in the preparation of radioprotective agents to block radioactive iodine uptake by the thyroid gland during nuclear emergencies. Also applied in some food preservation and processing methods due to its stable iodine release properties.
