This chemical, known as 2-APB, is primarily used in organic synthesis as a reagent for the protection of diols and carbohydrates, forming stable cyclic boronate esters that enable selective reactions in complex molecular structures. It is also utilized in the preparation of boron-containing compounds valuable for materials science and medicinal chemistry. In biological and biochemical research, 2-APB acts as an inhibitor of inositol 1,4,5-trisphosphate (IP₃) receptors and store-operated calcium entry (SOCE), playing a key role in studying calcium signaling pathways related to neuroscience, enzyme function, cancer, and other diseases. Its multifaceted role as a catalyst, intermediate, and pharmacological tool makes it essential in research and industrial applications.
