Used in pharmaceutical synthesis as a key intermediate in the preparation of kinase inhibitors, particularly for targeted cancer therapies. Its boronate ester functionality enables Suzuki-Miyaura cross-coupling reactions, allowing efficient construction of complex heterocyclic systems found in bioactive molecules. The SEM (trimethylsilylethoxymethyl) protecting group ensures selective reactivity during multi-step synthesis, making it valuable in the development of potent drug candidates targeting oncogenic signaling pathways.
