Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Serves as a building block in the development of antitumor agents due to its acridine core, which can intercalate DNA. Also employed in the design of kinase inhibitors and fluorescent probes for biological imaging. Its carboxylic acid group allows for easy functionalization and conjugation in drug discovery programs. Shows potential in materials science for developing organic semiconductors and optoelectronic materials.
