Used as a key intermediate in organic synthesis, particularly in the preparation of macrocyclic compounds and Schiff bases. Its two aldehyde groups allow for bifunctional reactivity, making it valuable in constructing coordination polymers and metal-organic frameworks (MOFs). It is also employed in the development of fluorescent dyes and sensors due to its aromatic structure, which can enhance photophysical properties. In pharmaceutical research, it serves as a building block for synthesizing heterocyclic compounds with potential biological activity. Additionally, it finds use in material science for creating conjugated systems in organic electronics.
