a vial is only as good as its paperwork
Analytical documentation is the product. Below is exactly what we test, what ships with each lot, and what you can request from us at any time.

how a lot gets released
four checkpoints, no exceptions- 01
synthesis & lyophilization
Material is produced by solid-phase synthesis, cleaved, purified and lyophilized under inert conditions before it is sealed into a vial.
- 02
reverse-phase hplc
Each lot is assayed by RP-HPLC. Peak-area purity is recorded and the chromatogram is retained against the lot number.
- 03
mass-spectrometry identity
Observed mass is compared to the expected sequence mass to catch truncations and misincorporations that a purity number alone will not surface.
- 04
release & documentation
Nothing ships without a lot-matched certificate of analysis. Randomised lots also go out to an independent laboratory.
what each check actually proves
hplc purity
Every lot is assayed by reverse-phase HPLC before release, and the chromatogram ships with the batch so you can verify the peak area yourself.
mass confirmation
Molecular identity is confirmed by mass spectrometry against the expected sequence mass, catching truncations and misincorporations that purity alone will not show.
cold chain
Material is lyophilized under inert conditions, sealed, and dispatched insulated so assay integrity survives transit.
independent testing
Randomised lots are sent to an independent analytical laboratory; those reports are available on request for any batch we have shipped.
what a certificate of analysis contains
Every shipment is lot-matched to its own document. If you need a copy for a batch you already hold, request it by lot number.
