Application

This compound is primarily employed as a key intermediate in the synthesis of complex organic molecules, particularly in pharmaceutical and agrochemical research. Its boronate ester group enables efficient cross-coupling reactions, facilitating the construction of biaryl structures. The THP-protected phenol enhances solubility and stability during multi-step syntheses. Researchers also use it to introduce boron-containing functionalities into target molecules for further derivatization.
