Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nonsteroidal anti-inflammatory drugs (NSAIDs) and other bioactive compounds. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building more complex molecules. Also employed in the preparation of dyes and fluorescent probes due to the presence of both amino and iodobenzene functionalities, which can participate in coupling reactions. Commonly used in research settings for labeling and tracer studies, especially where iodine-containing aromatic systems are needed.
