Used in pharmaceutical synthesis, particularly as an intermediate in the development of proteasome inhibitors for cancer treatment. It plays a key role in boron-containing drugs due to its ability to form reversible covalent bonds with biological targets. Commonly applied in the design of enzyme inhibitors, especially in oncology and anti-inflammatory therapies. Its structure supports enhanced binding affinity and selectivity toward specific proteases. Also utilized in medicinal chemistry for optimizing pharmacokinetic properties of boron-based therapeutics.
