Used primarily in organic synthesis, this compound serves as a key intermediate in the preparation of acridine-based derivatives with biological activity. It is employed in the development of fluorescent probes due to the inherent fluorescence of the acridine ring, useful in biochemical and cellular imaging. Its reactivity allows for the introduction of acridine moieties into larger molecules, making it valuable in the synthesis of potential antitumor and antimicrobial agents. It is also utilized in the production of dyes and optical brighteners where stable, aromatic frameworks are required.
