Used as a building block in organic synthesis, particularly in the preparation of ligands for catalytic reactions. Its rigid biphenyl structure and carboxylic acid functional groups allow it to act as a precursor in metal-organic frameworks (MOFs) and coordination polymers. It is also employed in the development of specialty polymers and functional materials where controlled molecular geometry and polarity are required. Additionally, derivatives of this compound find use in pharmaceutical research due to their potential to influence biological activity when incorporated into larger molecular systems.
