Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. The iodine substituent allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex aromatic structures. Commonly employed in the development of medicinal agents where aryl-aryl bonds are needed. Also utilized in radiolabeling studies due to the presence of iodine, making it suitable for tracer applications in metabolic and imaging research. Its amide group provides polarity and hydrogen-bonding capability, useful in modifying solubility and binding properties in drug design.
