Physical Properties
GHK-Cu is a copper-binding tripeptide (Gly-His-Lys) that forms a stable 1:1 complex with copper(II). The free-peptide molecular weight is 340.38 Da; the copper complex is most commonly cited near 403.9 Da. It is studied as a matrikine involved in tissue remodeling.
Analysis & Documentation
Identity
Each production lot is checked against the reference structure recorded for this compound:
- Classification — Copper(II) tripeptide complex
- Molecular formula — C₁₄H₂₄CuN₆O₄
- Expected mass — ~403.9 Da (copper complex)
- CAS registry — 49557-75-7
- Chain length — 3 amino acids
- PubChem CID — 73587 (GHK peptide)
Analytical Methods
Testing is carried out per lot by an independent laboratory. The methods measure what the material is and how much of it is the target compound:
- RP-HPLC — reverse-phase separation of the target from process-related impurities; purity is reported as area percent of the main peak
- Mass spectrometry — observed mass compared against the expected molecular mass above
- Retention time — compared against a reference standard run under the same conditions
- Chromatogram — reproduced on the certificate so the peak and any shoulders can be inspected directly
Material & Documentation
What arrives, and how to tie it back to its paperwork:
- Appearance as supplied — Solid oral capsule (research-grade GHK-Cu)
- Lot number — printed on the container label and used to look up the certificate
- Certificate — indexed by lot at Certificates of Analysis
