Used as a key intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in Suzuki-Miyaura cross-coupling reactions where the boronate ester group acts as a coupling partner for forming biaryl structures. Its aldehyde functionality allows further derivatization, enabling the construction of complex organic molecules. Commonly employed in medicinal chemistry for building blocks in drug discovery and in materials science for creating functional organic compounds. Stable and selective, it is favored in multi-step syntheses requiring orthogonal reactivity.
