Application

This compound serves as a key precursor in the synthesis of thyroid hormone analogs and radiopharmaceutical contrast agents due to its stable iodine moiety. In plant biology research, it functions as a synthetic auxin analog for studying growth regulators. The carboxylic acid group enables conjugation to biomolecules for targeted drug delivery systems, while the phenoxy component facilitates incorporation into liquid crystal materials and polymer modifiers.
