Purity figures published with each tested lot
IronRack Labs supplies research use only peptides and research chemicals to laboratories, universities and research businesses. Every tested lot is analyzed by an independent third party laboratory, and the lot number printed on the vial matches the certificate you can open on this site.
Third party tested
Applicable lots are analyzed by an independent laboratory.
Lot tracked
Inventory is associated with identifiable lot numbers.
Transparent testing
Reports are published for corresponding tested lots.
Secure checkout
Encrypted checkout with tracked domestic fulfillment.
Shop by category
Categories are grouped by chemical structure and molecule size, not by any outcome. Every listing is supplied for laboratory research use only.
Peptides with acylation, amidation, cyclization or metal complexation.
Analytical reference materials for identification and quantification.
The IronRack standard
Research. Precision. Integrity. Three words that decide what we publish, what we hold back and what we refuse to put in a box.
Applicable lots are sent to an independent third party laboratory. We do not report on our own material.
The certificate of analysis for your lot is available before you order and travels with the shipment.
Product, lot, report, inventory and order stay linked, so we can tell you which lot filled your order.
Held at minus 20 degrees Celsius, packed insulated, tracked to the door. We ship within the United States only.
Popular research materials
Each listing shows the labeled quantity, and every vial leaves with its lot number on the label, so the material on your bench can be matched back to its certificate of analysis.
Quality and testing
Nothing is listed on the strength of a supplier’s word. Applicable lots are run on two separate methods by an independent laboratory, and only reach the catalog once both agree.
A new lot is logged, held apart from sellable inventory and sampled.
C18 separation, detection at 214nm. The peak area is the published purity figure.
Measured molecular mass has to match the sequence on the label, or the lot fails.
Chromatogram, endotoxin and heavy metal screens published against the lot number.
The laboratory name, the method detail, the chromatogram, the endotoxin screen and the heavy metal screen appear in full on every certificate.

Applicable lots are analyzed by RP-HPLC, with LC-MS identity confirmation. The results, method detail and chromatogram for each lot are shown on its certificate of analysis.
Every vial is printed with a lot number. Enter it in the lot search on our COA page to open the matching certificate of analysis.
Move it to cold storage as soon as it arrives, at the temperature printed on the vial label. We do not provide preparation, reconstitution or administration guidance.
