Certificates of analysis
Every compound is listed. Where we hold the report supplied with a lot, it is rebuilt here as a technical document: the chromatogram drawn from its integration table, the peak table, the method, and the identity verified against PubChem. Purity is shown as printed on the report and never rounded up, and anything we corrected on the supplier’s document is listed with it.

What the purity figure is
The main peak’s share of the integrated peak area at the detection wavelength, which measures related impurities. Water, salts and counter-ions are not part of that figure. A certificate reports them as separate tests.
Check the lot number
Each document describes one manufacturing lot. Compare the lot number here with the one printed on your vial label.
Not listed, or a different lot
