Used as a tridentate ligand in coordination chemistry, particularly in the formation of transition metal complexes for catalytic applications. Its structure allows for strong chelation, making it effective in stabilizing metal centers in oxidation reactions and C–H activation processes. Commonly employed in the development of homogeneous catalysts for alkane functionalization and in biomimetic studies due to its ability to mimic natural enzyme active sites. Also utilized in the synthesis of metallo-supramolecular architectures and sensor systems for metal ion detection.
