GHK-Cu

Product Name:

GHK-Cu

Chemical Information:

• Compound Class: Synthetic tripeptide–copper(II) coordination complex
• Sequence: Gly-His-Lys (copper-bound tripeptide complex)
• Molecular Formula: C₁₄H₂₄CuN₆O₄
• Molecular Weight: ~404 g/mol (neutral copper complex)*
• *)Reported values for the neutral complex vary with the convention applied to copper coordination and with salt form. Depending on ionization conditions, mass spectrometry may also show a signal near 340 Da corresponding to the dissociated tripeptide; this reflects in-source dissociation and does not indicate the absence of copper. The blue to blue-green appearance is consistent with Cu(II) coordination. Exact molecular weight, identity and copper content for a given lot are stated on the lot-specific Certificate of Analysis.

Product Description:

GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a synthetic tripeptide-metal coordination compound composed of a defined three-amino-acid sequence (Gly-His-Lys) bound to a copper ion. The compound is produced through controlled synthesis and metal-complexation processes and is provided exclusively for in vitro research in qualified laboratory settings. GHK-Cu is structurally characterized and utilized in controlled experimental environments for analytical and experimental evaluation of peptide–metal coordination chemistry and associated physicochemical properties. It is supplied in lyophilized powder form to support stability and integrity during storage and handling. This material is not formulated for cosmetic, clinical, diagnostic, or therapeutic use.

Research Applications:

GHK-Cu is utilized in controlled laboratory research settings for applications such as:

• Analytical evaluation of peptide–metal complex structure and composition
