Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules with potential antitumor and antimicrobial properties. Its structure serves as a building block in heterocyclic chemistry, enabling the construction of complex isoquinoline-based compounds. It is also employed in research for developing fluorescent probes due to its ability to participate in condensation reactions that yield emissive products. Additionally, it finds use in the preparation of ligands for catalytic metal complexes in organic transformations.
