- Molecular Weight
- 3647 Da ±1 Da
- 711 Da ±1 Da
- Mass Spectrometry (ESI-MS or MALDI-TOF)
- Deviation >1 Da indicates wrong peptide or synthesis failure
- HPLC Purity
- ≥98% by area under curve
- Reverse-phase HPLC with UV detection at 214 nm
- Any result <97% fails research-grade standard
- Primary Peak Retention Time
- 18–22 minutes (column-dependent)
- 12–16 minutes (column-dependent)
- HPLC chromatogram analysis
- Peak should be baseline-separated from impurities
- Appearance (Post-Reconstitution)
- Clear, colourless solution
- Visual inspection
- Cloudiness or colour indicates contamination or degradation
- Batch Number Format
- Alphanumeric with date code
- Label cross-reference
- Must match vial label exactly. Mismatches indicate mislabeling
- Accredited Testing Lab
- ISO/IEC 17025 certified facility
- Accreditation registry lookup
- Unaccredited labs have no enforcement mechanism for accuracy
