Understanding the peptide supply chain helps contextualize quality concerns, pricing, and regulatory requirements. This article maps the key stages from raw materials to finished product.

Stage 1: Raw Materials

Fmoc-Protected Amino Acids

The building blocks of solid-phase peptide synthesis. Major suppliers include companies in China, India, Japan, and Europe. Supply chain disruptions in amino acid production have historically impacted peptide manufacturing timelines.

Resins

Solid supports for SPPS. Wang resin, Rink amide resin, and chlorotrityl resins are commonly used. Resin quality directly affects synthesis efficiency.

Reagents and Solvents

Coupling reagents (HATU, HBTU, DIC), deprotection reagents (piperidine), cleavage reagents (TFA), and solvents (DMF, NMP, DCM) are consumed in large quantities.

Stage 2: Synthesis

Stage 3: Purification

Stage 4: Post-Processing

Stage 5: Formulation

Stage 6: Distribution
