(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2,3-dimethylbutanoic acid（Cat No.:M034227）is a specialized amino acid derivative featuring a fluorene-based protecting group (Fmoc) at the amino terminus. This compound is often used in solid-phase peptide synthesis (SPPS), where the Fmoc group protects the amino functionality during peptide assembly. The structure incorporates a chiral center at the α-carbon, along with a branched side chain of two methyl groups at the β-position. Its application is significant in peptide chemistry, particularly for creating peptides with tailored structures and bioactivities for pharmaceutical and biochemical research.
