N-Fmoc-L-isoleucine（Cat No.:R061176）is a protected α-amino acid commonly used in solid-phase peptide synthesis (SPPS). It features an Fmoc (9-fluorenylmethyloxycarbonyl) group at the N-terminus, which provides base-labile protection, enabling efficient and selective peptide chain elongation. As a derivative of the branched-chain amino acid L-isoleucine, it contributes hydrophobic and steric properties to peptide structures, influencing folding and bioactivity. N-Fmoc-L-isoleucine is supplied at high purity and is ideal for use in pharmaceutical development, custom peptide manufacturing, and biochemical research involving structure–activity relationship (SAR) studies and protein engineering.
