The pharmaceutical research and development (R&D) landscape is continuously seeking innovative molecular building blocks to create novel drug candidates. Among these, protected amino acids hold a special place, particularly those incorporating non-natural configurations like D-amino acids. Fmoc-D-4-Methoxyphenylalanine (CAS 201335-88-8) is a prime example of such a valuable intermediate, widely employed in the synthesis of peptides with enhanced therapeutic properties. This article highlights its importance in pharmaceutical R&D and provides guidance on sourcing this critical chemical.

Fmoc-D-4-Methoxyphenylalanine is a derivative of the amino acid phenylalanine, modified with a methoxy group on the phenyl ring and incorporating the D-configuration. The N-terminal Fmoc group is a standard protecting group in Fmoc-based solid-phase peptide synthesis (SPPS), a cornerstone technique in pharmaceutical research for rapidly assembling peptide chains. The D-configuration of the amino acid is significant; peptides containing D-amino acids often exhibit greater resistance to enzymatic degradation in the body compared to their L-amino acid counterparts. This characteristic can lead to improved pharmacokinetic profiles, such as longer half-lives and better oral bioavailability, making them more attractive as drug candidates. Consequently, Fmoc-D-4-Methoxyphenylalanine serves as a key intermediate for synthesizing peptides with enhanced stability and potentially improved therapeutic outcomes.
