Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of isoquinoline-based bioactive compounds. Its halogen substituents allow for selective cross-coupling reactions, enabling the construction of complex molecules for drug discovery. Commonly employed in research settings to prepare potential antitumor, antimicrobial, and anti-inflammatory agents. Also utilized in the preparation of ligands for catalytic processes and in the development of organic electronic materials due to its aromatic and electron-deficient character.
