The PureChems Standard

Six stages between powder and proof.

How each peptide is made, measured and verified, from synthesis to dispatch. This is what the price reflects.

Verified in-house & independently, with a Certificate of Analysis for every batch.
Cleanroom synthesis01
Cleanroom synthesis · SPPS · Fmoc

Built one bond at a time.

Each peptide is assembled residue by residue on a solid-phase support, inside a temperature- and humidity-controlled cleanroom.

Solid-phase · FmocClass-7 cleanroom
RP-HPLC purification02
RP-HPLC purification · RP-HPLC · 214 nm

Everything impure, removed.

Reverse-phase chromatography separates the target peptide from every truncation and by-product, until only the intended molecule remains.

214 nm detectionGradient elution
Mass-spec verification03
Mass-spec verification · ESI-MS · m/z

Proven, never promised.

Mass spectrometry confirms the exact molecular weight, and an independent laboratory verifies purity above 99% before a batch is released.

ESI-MS confirmed≥99% target
Lyophilization04
Lyophilization · Lyophilized · −50 °C

Locked in, perfectly still.

The purified peptide is freeze-dried into a stable powder at deep-cold temperatures, then sealed under inert gas.

−50 °C dryingInert-gas sealed
Certificate of Analysis05
Certificate of Analysis · COA · per batch

Documented and verified.

Each product is tested by an independent laboratory. Its Certificate of Analysis, with the HPLC and Mass Spec results, available on request.
