Used as a chelating ligand in coordination chemistry, particularly in the formation of complexes with transition metals such as iron, ruthenium, and copper. Its hydroxymethyl group allows for further functionalization or anchoring to solid supports, making it useful in catalysis, especially in homogeneous and immobilized catalytic systems. Applied in the development of sensors due to its ability to bind metal ions with high selectivity, influencing optical or electrochemical responses. Also explored in the design of metallo-drugs and bioactive complexes where controlled metal binding is required. Its structural features support use in supramolecular chemistry for constructing molecular assemblies and switches.
