Used as a key intermediate in the synthesis of bidentate ligands for transition metal catalysts, particularly in palladium-catalyzed cross-coupling reactions. Its chloromethyl group allows for easy functionalization and attachment to solid supports or polymers, making it valuable in heterogeneous catalysis. Also employed in the preparation of metallo-supramolecular compounds and coordination polymers due to its ability to chelate metal ions effectively. Its structural features support the development of luminescent materials and sensors based on metal complexes.
