Quality & Verification

Documented, not claimed.

Every synthesis run passes three-stage control, and every shipment carries a batch-specific certificate of analysis. Here is exactly what that means — and how you can verify it.

The pipeline

Three stages, zero shortcuts.

01

Raw material screening

Incoming amino acids, resins and reagents are checked against specification before a single coupling starts. Off-spec lots never enter synthesis.

  • Identity confirmation
  • Purity by HPLC
  • Moisture / residual solvents

02

In-process monitoring

Solid-phase synthesis is monitored at defined checkpoints. Intermediates are sampled and characterized before the chain is allowed to continue.

  • Coupling efficiency
  • Intermediate characterization
  • Cleavage & precipitation QC

03

Final HPLC-MS verification

The finished batch is analyzed for identity, purity and quantitative fill. Only lots that pass every criterion are released.

  • Identity by mass spectrometry
  • Purity by HPLC
  • Quantitation per vial

ISO 9001:2015 certified quality management · analytical methods: HPLC-UV, LC-MS

Certificate of Analysis

What every COA contains.

Each shipment includes a batch-specific Certificate of Analysis. It documents the analytical results of the exact lot you receive — not a generic template.

  • Lot number

    Ties the certificate to one physical batch

  • Identity

    Confirmed by mass spectrometry (molecular weight match)

  • Purity

    Quantified by HPLC, reported as % area

  • Quantitation

    Actual mg per vial, with tolerance band

  • Analytical method

    HPLC-UV / LC-MS parameters and conditions
