Used primarily in organic synthesis, it serves as a reagent for the preparation of various iodine-containing compounds. It is also employed in the pharmaceutical industry for the synthesis of active pharmaceutical ingredients (APIs) that require iodine incorporation. Additionally, it finds application in the development of liquid crystal materials, where it acts as a key intermediate. Its role in the production of dyes and pigments is notable, particularly in creating iodine-based colorants. In research, it is utilized for studying reaction mechanisms involving iodine and amine groups.
