Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure, featuring amino and iodo groups, allows for selective functionalization, making it valuable in medicinal chemistry for creating targeted drug candidates. Commonly employed in research settings for designing compounds with potential anticancer, antiviral, or anti-inflammatory properties. Also utilized in the preparation of labeled compounds for metabolic studies due to the presence of iodine, which facilitates detection and imaging. The iodo substituent enables efficient copper- or palladium-catalyzed cross-coupling reactions to form carbon-carbon or carbon-heteroatom bonds.
