Used as a building block in organic synthesis, particularly in the preparation of coordination compounds and metal-organic frameworks (MOFs). Its three carboxylic acid groups allow for strong chelation with metal ions, making it valuable in catalysis and material science. Also employed in the development of functional polymers and resins due to its rigid aromatic structure and multiple reactive sites. Investigated for use in gas storage and separation technologies owing to its ability to form porous networks when linked with metal centers.
