2-Iodophenylboronic acid is widely used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, where it serves as a key building block for creating biaryl compounds. These compounds are essential in the development of pharmaceuticals, agrochemicals, and advanced materials. The iodine substituent on the phenyl ring enhances reactivity, making it a versatile intermediate for further functionalization. Additionally, it is employed in the synthesis of complex organic molecules, including natural products and polymers, due to its stability and compatibility with various reaction conditions. Its role in medicinal chemistry is notable, as it aids in the design of drug candidates with improved efficacy and selectivity.
