Used in the synthesis of acridine-based pharmaceuticals, particularly in the development of antitumor and antimicrobial agents. Its structure supports intercalation into DNA, making it valuable in research on anticancer compounds. Also employed as an intermediate in the preparation of fluorescent dyes and sensors due to its conjugated aromatic system. Active in studies targeting topoisomerase inhibition, which plays a role in controlling cell replication. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies of acridone derivatives.
