Certificates of analysis for every batch
No lot is released without a full certificate: HPLC purity, MS identity and endotoxin screening, issued against the batch number printed on your vial.
What's on a certificate
Gradient reverse-phase chromatography with area-percent reporting — the ≥ 99.0% figure on the vial, with the raw chromatogram attached.
Electrospray mass spectrometry confirms the measured molecular ion against the theoretical mass of the compound.
Kinetic LAL screening on every lot — current release limit: < 0.05 EU/mg.
The exact analytical procedure used (e.g. HPLC + ESI-MS), so your lab can reproduce the measurement.
The independent laboratory that ran the verification — all current lots are issued by North Analytics.
The lot identifier linking your vial, this certificate and the retained sample in our archive.
How to verify a batch
- Find the batch number printed on your vial label — it looks like BP-2417-A.
- Open the product page and switch to the Certificate of Analysis tab (or scan the QR code on the box in production shipments).
- Match the batch number and compare the reported HPLC, MS and endotoxin values against the certificate.
- Optional: re-run HPLC on your own instrument — our published figures are the release figures, so results should agree within instrument tolerance.
Documents for every current lot are listed below. For archived batches, methodology questions or the underlying chromatograms, contact the QC team with the batch number.
