A certificate that only reports a purity percentage is telling you a fraction of the story. Ours carry six sections.
| Identity | Mass-spec confirmation against theoretical MW |
| Purity | RP-HPLC area percent, in-house and third-party |
| Net content | Peptide content by nitrogen analysis, salt-corrected |
| Water | Karl Fischer titration |
| Contaminants | Endotoxin (LAL), residual solvent (GC), heavy metals (ICP-MS) |
| Chain of custody | Synthesis date, lot number, analyst, release signature |
Each compound has a GHS-format safety data sheet covering hazard identification, first-aid measures, handling and storage, exposure controls, physical properties, stability, and disposal.
Lyophilized peptides are fine powders that can become airborne when a vial is opened. Handle in a fume hood or biosafety cabinet, wear nitrile gloves and eye protection, and avoid generating dust. Consult the SDS for the specific compound before first use.
