Open AssayIndex, Where Peptide Purity Meets the Fine Print
An open index of third-party analytical results for research peptides, with searchable records, supplier rollups, laboratory comparisons, anomalies, and downloadable data.
Field notes
The index converts buyer- and laboratory-submitted assay reports into a shared record format, then derives rollups by batch, compound, supplier, lab, and quarter. Its coverage includes 6,584 reports across 1,154 batches and 66 compounds, while the recovery measure appears on only 3,813 records. The site also exposes methods, provenance, limitations, anomalies, and a supplier comparison with thirteen columns and row-level confidence flags.
