This chemical is widely utilized as a chelating agent in the synthesis of metal complexes, particularly in coordination chemistry, due to its ability to form stable complexes with various metal ions. It serves as a key building block in the development of luminescent materials, where its derivatives are employed in the design of organic light-emitting diodes (OLEDs) and sensors for detecting metal ions. Additionally, it is used in supramolecular chemistry for constructing molecular frameworks and host-guest systems. Its aldehyde groups enable further functionalization, making it valuable in the preparation of Schiff bases and other organic compounds for applications in catalysis and material science.
