How a lot reaches this catalog.
Solid phase, monitored
Fmoc chemistry on 2-chlorotrityl or Rink amide resin. Coupling is monitored stepwise; a failed cycle ends the run rather than getting capped and carried forward.
Fmoc/tBu≥ 99.5% stepwise
Pooled on purity
Preparative RP-HPLC over C18, acetonitrile against 0.1% TFA. Fractions are pooled on purity, not yield - the tail of the peak is discarded even when it would pass.
Prep RP-HPLCAcetate exchange
Someone else’s instrument
Each lot is sampled and sent to an independent laboratory, which reports purity, identity and content. We do not run our own release assay.
Independent laboratoryOne lot per size
Sealed, seated, tracked
Vials ship seated in a moulded insert inside a rigid outer, with the packing note carrying every lot number. Lyophilised material is stable at ambient temperature in transit, so no coolant is used.
Moulded insertTracked dispatch
The page never comes down
The certificate goes online the day the lot is released and stays there after it sells out, is superseded, or is withdrawn. Withdrawn lots keep their page and gain a dated note.

04 · The register
What every lot on this site has been through.
The rules the catalogue is sold against. Each one is checkable on the certificate it produces.
Purity, identity and content, every lot
Purity by HPLC with the chromatogram on the report, identity, and the content of the vial in milligrams against its label. Each size is its own lot with its own report.
Assayed by a laboratory we do not own
The laboratory’s name and report number are printed on every report, and the report is published as the laboratory issued it. No lot is released on our own measurement.
Published first, never removed
The certificate goes online at a permanent address before the first vial ships. It stays after the lot sells out. A withdrawal is dated on the page and every recipient is told.
One report per size
Each size is its own lot with its own lab report. A report stays published after its lot sells out.
05 · Terms of supply
For laboratory research use only. Not for human consumption.
Material is sold as a laboratory reagent to qualified investigators, institutional laboratories and commercial R&D groups, for in-vitro work and non-human in-vivo studies under an approved protocol.
Read the full policyWhat we will not do
No therapeutic, diagnostic or preventive claims. No dosing guidance, protocols or administration instructions, and no answers to questions about personal use.
Regulatory status
None of these compounds is approved by the FDA for human use, and none is supplied as a drug, food, cosmetic or dietary supplement. Purchasers are responsible for compliance in their own jurisdiction.
If a lot fails after release
The lot is withdrawn, every recipient is notified, and the certificate page gains a dated withdrawal note. Material is replaced or refunded at your choice, including shipping.
