Used as a key intermediate in the synthesis of pharmaceuticals and bioactive compounds, particularly in the development of peptide-based drugs. Its structure allows for selective protection of amines in multi-step organic syntheses, making it valuable in solid-phase peptide synthesis. Commonly employed in research settings for modifying amino groups in complex molecules, it helps improve solubility and stability during reaction processes. Also utilized in the preparation of fluorescent probes due to the fluorenyl group, enabling detection and imaging in biological systems.
