In the dynamic field of peptide synthesis, the choice of amino acid derivatives plays a pivotal role in the success of creating complex peptides. Among these crucial building blocks, Fmoc-D-4-Methoxyphenylalanine stands out. This article delves into its significance, properties, and applications for researchers and procurement managers seeking high-quality materials for their projects.

Fmoc-D-4-Methoxyphenylalanine, identified by CAS number 201335-88-8, is a protected D-amino acid derivative. The N-terminal Fmoc (9-fluorenylmethoxycarbonyl) group serves as a versatile protecting group, essential for stepwise peptide chain elongation using the Fmoc strategy in solid-phase peptide synthesis (SPPS). The inclusion of the D-configuration of methionine-substituted phenylalanine introduces unique structural characteristics to the resulting peptides, often conferring increased resistance to enzymatic degradation and altering pharmacokinetic profiles. This makes it a valuable component for developing more stable and potent peptide therapeutics.
