PubChem lists GHK-Cu as Prezatide Copper with CAS 89030-95-5, molecular formula C₁₄H₂₃CuN₆O₄⁺, and molecular weight approximately 402.92 g/mol.

Research Applications

Analytical characterization using HPLC, UPLC, LC-MS, and suitable spectroscopic workflows

Investigation of copper-peptide coordination chemistry

Evaluation of Cu(II)-GHK metal-ligand interactions under controlled conditions

Comparative analysis of GHK and copper-complexed GHK

Characterization of peptide-metal binding and coordination behavior

Assessment of molecular identity, purity, copper association, and structural integrity

Evaluation of chromatographic and spectrometric characteristics of copper-peptide complexes

Investigation of concentration-dependent molecular interactions in defined in vitro systems

Stability profiling under controlled temperature, pH, buffer, light, and storage conditions

Quality Documentation

A batch-specific Certificate of Analysis and applicable analytical documentation should be available for each lot. Verify tripeptide identity, copper coordination, purity, molecular representation, counterion content, formulation details, and batch information against the records supplied with the individual product.

GHK-Cu requires extra care when reporting the molecular formula and molecular weight because reference databases and commercial materials list several chemically valid representations. PubChem's Prezatide Copper record reports C₁₄H₂₃CuN₆O₄⁺ and 402.92 g/mol, while other coordination/protonation representations produce different nominal masses.

GHK-Cu acetate is also a distinct preparation. Cayman Chemical lists the monoacetate form separately under CAS 300801-03-0 with formula C₁₄H₂₂CuN₆O₄·C₂H₄O₂ and formula weight approximately 462.0 g/mol. The free complex and acetate preparation should therefore not be treated as analytically identical.

Batch-specific chromatographic, spectrometric, and copper-content documentation should be used as the final reference for product specifications.
