Used primarily in cross-coupling reactions, this compound serves as a key building block in the synthesis of pharmaceuticals and organic electronic materials. Its boronate ester group enables efficient Suzuki-Miyaura coupling, allowing the formation of biaryl and heteroaryl structures found in bioactive molecules. It is particularly valuable in drug discovery for constructing complex thiazole-containing scaffolds. Additionally, it finds use in materials science for developing fluorescent dyes and organic semiconductors due to the electron-accepting nature of the benzo[d]thiazole core.
