Used as a tridentate ligand in coordination chemistry, forming stable complexes with transition metals such as copper, nickel, and cobalt. Its three sulfur donor atoms allow for strong chelation, making it valuable in catalysis and in the design of metalloenzyme mimics. Commonly employed in the development of molecular sensors and redox-active compounds due to its electron-donating properties. Also investigated in supramolecular chemistry for constructing metal-organic frameworks and cage-like structures.
