PASSHow we verify quality
Purity is measured by reverse-phase HPLC against a qualified reference standard, and the SR-17018 assay is reported on the batch certificate of analysis. Our internal specification is ≥ 99% by HPLC, above the ≥ 98% minimum that has been common in the research-reagent market for SR-17018. Batches that fall below 99% are not released.
Analytical work is performed by an independent third party, not in-house, so the COAs you receive are third-party verified. Current batch COAs are published publicly, and additional batch documentation is available on request.
