The specifications every lot is released against. Figures we cannot yet substantiate are not shown.
| Chromatographic purity | ≥99% |
|---|---|
| Endotoxin | ≤0.05 EU/mg |
| USP <71> sterility incubation | 14 days |
Every lot is released against a written specification and accompanied by the analytical package that demonstrates it. Identity is confirmed by mass spectrometry; purity is measured by reversed-phase HPLC and reported as a percentage of total peak area at 214 nm.
A certificate that reports a purity figure without the chromatogram behind it is a claim, not a measurement. Ours ship with both.
Where a figure below is absent, it is because we do not yet hold the data to support it — not because it is unfavourable. It will appear here when released lots supply it.
