Sodium iodide is widely used as an iodide-ion source in iodometric titrations, which are essential in quantitative analysis in various fields, including environmental testing and food safety. It serves as a reference compound in iodine-fortification research, particularly in the food and pharmaceutical industries, where iodine is a critical nutrient. Additionally, sodium iodide is utilized in the production of iodinated contrast media for medical imaging and in the synthesis of other iodide compounds. Its applications extend to the field of radiopharmaceuticals, where it is used in the preparation of sodium iodide I-131 for thyroid imaging and treatment.
