In the complex world of biochemical manufacturing, understanding the chemistry and supply chain of key intermediates is vital for ensuring product quality and research success. Fmoc-D-4-Methoxyphenylalanine (CAS 201335-88-8) is one such critical compound, widely utilized in peptide synthesis. This article explores its chemical characteristics, applications, and the advantages of sourcing it from established manufacturers, particularly those in China.

Fmoc-D-4-Methoxyphenylalanine is an N-protected D-amino acid derivative. Its structure features a phenylalanine backbone with a methoxy group attached to the para-position of the phenyl ring and the unnatural D-stereochemistry. The N-terminal Fmoc group is a standard protecting group in solid-phase peptide synthesis (SPPS) that is stable under typical coupling conditions but can be readily removed with a mild base, such as piperidine. This orthogonal protection strategy is fundamental to building peptide chains incrementally. The D-configuration and the methoxy substitution contribute to unique properties in the final peptide, such as increased resistance to enzymatic degradation, which is highly desirable for therapeutic peptides aiming for longer in-vivo half-lives.
