Used as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. Its structure allows for selective modification to target specific enzymes involved in tumor growth and signal transduction pathways. Commonly employed in medicinal chemistry for optimizing potency and selectivity in drug candidates. Also utilized in the preparation of compounds with antiviral and anti-inflammatory activities. Its iodine moiety enables further functionalization through cross-coupling reactions, making it valuable in combinatorial chemistry and library synthesis for high-throughput screening.
