Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other bioactive molecules. Its boronate ester group enables Suzuki-Miyaura cross-coupling reactions, making it valuable in creating complex organic compounds. It is also employed in materials science for designing advanced polymers and coatings. Additionally, it serves as a building block in medicinal chemistry for drug discovery, aiding in the modification of molecular structures to enhance drug efficacy and selectivity. Its sulfonyl group further contributes to its utility in creating sulfonamide-based drugs, which are widely used in treating bacterial infections and other diseases.
