Used as a key building block in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to construct conjugated organic frameworks. It is widely applied in the preparation of metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), where its aldehyde and boronate ester groups allow for sequential functionalization and extended network formation. The dual boronate ester groups enable palladium-catalyzed coupling with aryl halides, while the aldehyde group can undergo further transformations such as imine formation or reduction, making it valuable in designing porous materials for gas storage, catalysis, and sensing applications. Its well-defined geometry supports the creation of ordered, stable structures in materials chemistry.
