Used as a key intermediate in the synthesis of functional organic materials, particularly in the preparation of conjugated polymers and metal-organic frameworks (MOFs). Its brominated aromatic structure enables cross-coupling reactions, such as Suzuki or Heck reactions, allowing the introduction of various functional groups for advanced material design. Also employed in the development of flame-retardant compounds due to the presence of bromine atoms. Its ester groups provide sites for further chemical modification, making it valuable in pharmaceutical and agrochemical research for building complex molecular architectures.
