Used in photodynamic therapy research, this compound serves as a prodrug for protoporphyrin IX (PpIX), a photosensitizer that generates reactive oxygen species upon light exposure. The Fmoc group enhances cellular uptake and provides stability, making it useful in targeted cancer treatments and dermatological applications. It is also employed in bioconjugation strategies for developing fluorescent probes and drug delivery systems in organic and peptide synthesis environments. Its role in synthesizing functionalized porphyrins supports advancements in imaging and therapy combinations (theranostics).
