Certificates of Analysis
Every lot we sell is tested by an independent laboratory before it is released. Here is what we test, and how to get the report for your vial.
Last updated 20 July 2026
What we test
Identity — mass spectrometry. Confirms the material is the compound named on the label, by matching the observed mass against the theoretical mass.
Purity — HPLC. Reports chromatographic purity as a percentage of total peak area. Our release threshold is 99%.
Testing is carried out by Janoshik Analytical, an independent laboratory we do not own or control.
How to read a CoA
Lot / batch number — ties the report to the specific production run your vial came from. A CoA for a different lot tells you nothing about yours.
Test date — when the analysis was performed.
HPLC chromatogram — the trace itself, with the main peak and any impurity peaks. The reported purity is the main peak as a share of total area.
MS spectrum — the observed mass, which should match the theoretical molecular weight of the named compound.
Getting the CoA for your lot
Email support@cylixlab.com with your order number and the lot number printed on the vial, and we will send the report for that specific lot. We aim to respond within 12–24 hours during Mon–Fri, 9am–6pm EST.
You can also request the CoA for a lot before ordering — tell us which compound you are looking at and we will send the report for the lot currently in stock.
A note on what a CoA does and does not tell you
A Certificate of Analysis describes the chemical identity and purity of a specific lot at the time it was tested. It is an analytical document and nothing more.
It is not evidence of safety or efficacy in humans or animals, and it does not change the fact that these materials are supplied for in-vitro laboratory research only. See our Research Use Only disclaimer.
