PeptiPro Does Not Self-Certify Purity

Our reagent is submitted to an independent, accredited analytical laboratory before release. The resulting Certificate of Analysis is the primary deliverable — available in full before any purchase commitment.

/ Certificate of Analysis

Full Analytical Data, Upfront

PeptiPro publishes complete analytical data before purchase. No request forms, no sales-call gatekeeping — batch-level traceability is standard, not a premium.

HPLC Chromatography

Mass Spectrometry Confirmation

Batch Reference Traceability

ESI-MS or MALDI data verifies molecular weight against the reference standard, ruling out structural isomers and confirming compound identity at the molecular level.

Each COA carries a unique batch number cross-referenced to the testing laboratory's report, providing an unbroken audit trail from synthesis to delivery.

High-performance liquid chromatography confirms identity and quantifies purity to the 99.5% threshold at minimum, with full peak-area data included.

/ Independent Testing

Third-Party Labs. No Exceptions.

PeptiPro retains accredited external analytical laboratories with no commercial affiliation to the synthesis source. This structural separation is what makes the data defensible.

Qualified procurement officers receive the full COA package — chromatograms, spectra, and batch reference — prior to order confirmation. The document is not a post-sale courtesy; it is a pre-sale requirement.
