Used in organic synthesis as a building block for pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its boronic acid group enables Suzuki-Miyaura cross-coupling reactions, making it valuable in creating biaryl structures found in drug candidates. Also applied in the synthesis of fluorescent probes and sensors due to its ability to interact with diols and participate in selective binding reactions. Its nicotinamide moiety supports interactions in biological systems, enhancing utility in medicinal chemistry research.
