In the complex world of pharmaceutical research and development, the quality of starting materials can make or break a project. For those involved in peptide synthesis and the creation of novel therapeutics, sourcing high-purity amino acid derivatives is non-negotiable. One such critical compound is (4S)-4-N-Fmoc-amino-1-Boc-L-proline, identified by its CAS number 174148-03-9.

This specific proline derivative is a highly functionalized building block, featuring both the Fmoc group on its amino moiety and a Boc group on the proline nitrogen. This dual protection strategy is indispensable for controlled peptide chain elongation, particularly in solid-phase peptide synthesis (SPPS). The Fmoc group, removable by mild bases, allows for sequential coupling, while the Boc group protects the internal nitrogen of proline, preventing unwanted reactions during synthesis.
