The catalog

Pick a compound.
Read its lot.

The lot number is printed on every label. Match it against the certificate — the numbers should agree exactly, or don't buy the vial.

Verification

Every lot goes
on the record.

  • 01A sample is pulled from every finished lot before any of it is listed for sale.
  • 02It goes to an accredited third-party lab, never an in-house bench and never the synthesis partner.
  • 03The certificate is published against the lot number. If a lot doesn't clear, it doesn't ship.

From synthesis to your bench

Four stops.
No shortcuts.

Numbered because the order matters — nothing gets labeled before it's tested, and nothing gets listed before it's labeled.

01

Synthesis

Solid-phase synthesis at a contracted facility, then reverse-phase purification and desalting.

02

Fill & lyophilize

Vialed under nitrogen, freeze-dried to a stable cake, crimp-sealed and printed with its lot.

03

Independent testing

A pulled sample goes out for HPLC and mass spec. The result gets published, pass or fail.

04

Cold-pack dispatch

Gel packs, insulation, tracked label. Out the door the same day on orders placed before 2PM CT.

Questions

Before you order.

Everything on this site is sold as a laboratory reagent. These are not drugs, supplements, foods, or cosmetics. They have not been evaluated by the FDA, and they are not intended for human or veterinary use of any kind. Orders are accepted from qualified researchers and institutions only.

No. We do not provide dosing, administration, protocol or usage guidance of any kind, and our support team is not permitted to answer those questions. We can only discuss what a compound is, what the certificate says about it, and how to store and handle the vial.

Qualified researchers, laboratories, universities and institutions. By placing an order you confirm you are 21 or older, that you are purchasing for legitimate laboratory research, and that you accept responsibility for lawful handling, storage and disposal.

Research chemicals are legal to purchase for laboratory use in most of the United States, but rules vary by state and by country, and some destinations restrict import entirely. You are responsible for knowing and following the law where you are. If you are unsure, check before you order.

It is your acknowledgement that you are a qualified researcher and that the materials are for laboratory research only. We record it with the order. Without it, the order cannot be placed.

No. We sell laboratory reagents to researchers. We do not market these products for personal use and we will cancel and refund any order where the intent is clearly outside laboratory research.
