Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds for constructing biaryl and heteroaryl frameworks. Its boronic acid functionality allows it to react with aryl or heteroaryl halides under palladium catalysis, making it valuable in pharmaceutical and agrochemical research for developing complex aromatic systems. The chloro and thiophene groups enhance electronic properties and binding selectivity, useful in materials science for tuning optoelectronic behavior in organic semiconductors. Also employed as a building block in drug discovery due to the prevalence of benzothiophene motifs in bioactive molecules.
