Used as a key intermediate in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions due to the presence of the boronate ester group. Its aldehyde functionalities allow for further derivatization, making it valuable in constructing conjugated organic frameworks such as covalent organic frameworks (COFs) and other porous materials. Commonly employed in the development of optoelectronic materials, sensors, and organic semiconductors owing to its extended π-conjugation and structural tunability. The compound’s ability to form imine or hydrazone linkages enables its use in dynamic covalent chemistry and the design of functional polymers.
