Used as a key intermediate in the synthesis of metal-organic frameworks (MOFs), particularly for constructing functional porous materials with applications in gas storage, separation, and catalysis. Its aldehyde and bromo functional groups allow for post-synthetic modifications, such as Suzuki or Sonogashira couplings, enabling the introduction of specific moieties to tailor material properties. Also employed in the preparation of fluorescent polymers and optoelectronic materials due to its ability to participate in condensation reactions forming conjugated systems. Its rigid aromatic structure supports the development of chemically stable networks useful in sensor design and environmental monitoring.
