Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly targeting BTK (Bruton's tyrosine kinase) for the treatment of autoimmune diseases and certain cancers. Its boron-containing structure enhances binding selectivity and potency in drug candidates. Also explored in prodrug formulations due to improved solubility and metabolic stability. Commonly applied in structure-activity relationship (SAR) studies to optimize pharmacokinetic properties in oncology and inflammation pipelines.
