Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and functionalized aromatic compounds. Its aldehyde and amide groups allow for dual reactivity, enabling conjugation reactions such as Schiff base formation or nucleophilic additions. Commonly employed in the development of bioactive molecules, including potential antitumor and antimicrobial agents. Also utilized in material science for constructing covalent organic frameworks (COFs) due to its rigid aromatic structure and reactive functional groups.
