This chemical is primarily utilized in organic synthesis, particularly in cross-coupling reactions such as Suzuki-Miyaura coupling. It serves as a key intermediate for constructing complex molecules, especially in pharmaceutical research and development. Its boronic ester group enables efficient formation of carbon-carbon bonds, making it valuable for creating diverse heterocyclic compounds. Additionally, it is employed in the synthesis of biologically active molecules, including potential drug candidates, due to its ability to introduce the azaindole moiety, which is often found in compounds with therapeutic properties. Its tosyl group further enhances its reactivity and selectivity in various chemical transformations.
