01
Synthesis · SPPS · Fmoc
Built one bond at a time
Every peptide is assembled residue by residue on a solid phase, in a temperature- and humidity-controlled Class 7 cleanroom.
Our Process
The PureChems Standard
Six steps between powder and proof.
How every peptide is made, measured and verified — from synthesis to dispatch. This is exactly what the price reflects.
Verified in-house and independently — a Certificate of Analysis with every batch.
02
Purification · HPLC
Separated to purity
The crude peptide is cleaved from the resin and purified by preparative HPLC until only the target molecule remains.
03
Verification · HPLC · MS
Measured, not estimated
Mass spectrometry confirms identity and analytical HPLC confirms purity. No peptide moves on without the numbers.
04
Lyophilisation
Frozen into a stable form
The purified solution is freeze-dried into a fine, stable powder — ready for long-term storage without loss of potency.
05
Sterile filling
Sealed in a clean environment
The powder is dosed and the vials are sealed on a sterile line — it reaches you at exactly the amount and purity it left the lab.
06
Certificate & dispatch
Proven, then shipped
Every batch receives a Certificate of Analysis — both in-house and independent. Only then is it packed and shipped.
