Application
1,2,4,5-Benzenetetracarboxylic acid is extensively used as a ligand in the synthesis of a wide range of metal-organic frameworks (MOFs) and coordination polymers. It can also be used to prepare supramolecular hydrogels by synthesizing gelators reacting 1,2,4,5-benzenetetracarboxylic acid with 4-hydroxy pyridine.

It is widely accepted that preconditioning procedures are indispensable in capillary electrophoresis in order to achieve reproducibility of migration times and peak areas. Several preconditioning strategies have been employed for electrophoretic determinations of inorganic anions using indirect UV detection including
