1,2,4,5-Benzenetetracarboxylic acid, also known as pyromellitic acid, is a white powder used as a ligand in the synthesis of metal-organic frameworks (MOFs) and coordination polymers. It is a benzene ring with four carboxylic acid groups attached at the 1, 2, 4, and 5 positions.
Common uses
- Ligand: Extensively used as a ligand for creating metal-organic frameworks (MOFs) and coordination polymers.
- Supramolecular Chemistry: Can be used to create supramolecular hydrogels by reacting with other compounds like 4-hydroxy pyridine.
- Chemical Synthesis: Serves as a building block in organic synthesis.
