This chemical is primarily used in peptide synthesis as a protecting group for amino acids. The fluorenylmethoxycarbonyl (Fmoc) group attached to the compound helps in selectively blocking the amino group during the synthesis process, ensuring the correct sequence of amino acids in the peptide chain. Its cyclopentene structure provides stability and facilitates efficient deprotection under mild basic conditions, making it suitable for solid-phase peptide synthesis (SPPS). This compound is particularly valuable in the production of complex peptides and proteins for pharmaceutical research and drug development.
