Used as a key intermediate in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to construct biaryl frameworks found in pharmaceuticals and agrochemicals. Its protected ortho-substituted phenol group allows selective functionalization in complex molecule assembly. The boronate ester is valued for its stability and reactivity under mild conditions, making it suitable for multi-step synthesis of bioactive compounds. Commonly employed in the development of drug candidates where aryl boron derivatives serve as versatile building blocks.
