For researchers and procurement specialists in the pharmaceutical and biotechnology sectors, the meticulous selection of amino acid derivatives is paramount to the success of peptide synthesis projects. Among these crucial building blocks, Boc-protected amino acids play a pivotal role, offering a protected N-terminus that allows for controlled chain elongation. Specifically, Boc-D-Pro-OSu (CAS: 102185-34-2), also known as N-Boc-D-proline Succinimidyl Ester, stands out as a valuable reagent for introducing the D-proline moiety into growing peptide chains. Understanding its characteristics and application benefits is key to optimizing your synthesis workflow.

The utility of Boc-D-Pro-OSu stems from its dual functionalization: the tert-butyloxycarbonyl (Boc) group protects the alpha-amino group of D-proline, preventing unwanted side reactions during coupling. Simultaneously, the N-hydroxysuccinimide (OSu) ester activates the carboxyl group of D-proline, rendering it highly reactive towards nucleophilic attack by the free amine of another amino acid or peptide fragment. This inherent reactivity makes it an excellent choice for efficient peptide bond formation, particularly in solid-phase peptide synthesis (SPPS), where controlled addition of protected amino acids is standard practice.

When sourcing essential reagents like Boc-D-Pro-OSu, partnering with a reputable manufacturer and supplier is critical.
