Used in organic synthesis as a building block for Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical development. Its boronic acid group facilitates coupling with aryl halides, making it valuable in creating biaryl compounds for drug discovery and materials science. The butylthio substituent enhances lipophilicity and electronic properties, useful in tuning the performance of organic semiconductors and bioactive molecules.
