Important aromatic carboxylic acid intermediate used as a synthetic raw material for pressure-sensitive recording paper, agricultural chemicals, and antioxidants. Its metal salts and complexes exhibit useful triboelectrical properties and are used as charge-control additives in dry xerographic toner formulations to control toner charging behavior.
