Boc-D-Phe-OH

Boc-D-Phe-OH is a cornerstone building block in Boc-strategy solid-phase peptide synthesis, enabling the reliable incorporation of D-phenylalanine residues into custom peptide sequences. The Boc protecting group in Boc-D-Phe-OH allows for selective coupling during peptide chain assembly while preventing unwanted side reactions at the amino functionality. As a D-amino acid derivative, Boc-D-Phe-OH is particularly valuable in the development of peptide-based pharmaceuticals and biologically active compounds where resistance to enzymatic degradation is desired. Whether used in research laboratories for exploring D-peptide biology or in pharmaceutical development for creating metabolically stable therapeutic peptides, Boc-D-Phe-OH delivers the stereochemical purity and batch-to-batch consistency that peptide chemists require.

Product Quality Assurance

Cosperpharm has established a comprehensive quality assurance system for Boc-D-Phe-OH that meets the rigorous expectations of peptide synthesis and pharmaceutical research applications:

Thorough analytical characterization. Each batch undergoes multi-technique analytical release testing: HPLC purity (≥98.0%), enantiomeric purity verification (≥99.5% a/a), optical rotation confirmation ([α]²⁰/D −25 ± 1°, c = 1% in ethanol), appearance verification (white to slight yellow to beige powder), and identity confirmation (IR).

Full batch traceability with retention samples. From raw material procurement through Boc protection, purification, drying, and final packaging, every step is fully documented and traceable. Each batch receives a unique lot number with sufficient retention samples maintained in accordance with Cosperpharm quality procedures.

Stability monitoring program. Cosperpharm conducts ongoing stability studies under recommended storage conditions (2–8 °C). Stability summaries are available to support customer quality requirements.

Documentation ready for quality systems. Every shipment includes a Certificate of Analysis (COA) with batch-specific purity and characterization data, a Safety Data Sheet (SDS), and customs documentation for international delivery. Custom quality agreements and additional documentation packages are available upon request.

Customer-initiated quality audits. Qualified customers are welcome to audit Cosperpharm's manufacturing, quality control, and documentation facilities. Please contact our regulatory team to schedule an audit.
