Core Molecular Specs & Technical Index

GHK-Cu copper peptide, scientifically known as glycyl-L-histidyl-L-lysine copper complex, is a tripeptide molecule naturally occurring in human plasma. For B2B buyers including cosmetic formulation chemists, contract manufacturers, and laboratory research directors, understanding the precise technical specifications of this raw material is essential for product development and quality assurance. The core value of GHK-Cu lies in its ability to deliver bioavailable copper ions to biological systems, supporting enzymatic processes and extracellular matrix maintenance.

Basic Properties and Molecular Characteristics

The GHK-Cu copper peptide molecule has a molecular weight of approximately 340.8 g/mol for the peptide backbone, with the copper complex increasing the overall mass. The compound appears as a blue-green crystalline powder due to the copper coordination. It is highly soluble in water at concentrations up to 10 mg/mL, making it suitable for aqueous formulations. The optimal storage conditions require temperatures between -20°C and 4°C in airtight, light-protected containers to maintain stability over extended periods.

Purity Specifications and Analytical Standards

Professional-grade GHK-Cu copper peptide must meet stringent purity requirements for commercial applications. The following technical indices represent industry-standard specifications for high-quality raw materials:

• Purity Level: Minimum 98% by HPLC analysis, with premium grades achieving 99% or higher for research applications
• Copper Content: 18.5% to 19.5% by weight, verified through atomic absorption spectroscopy
• Peptide Content: 80% to 85% net peptide, excluding counterions and water content
• Solubility: Clear solution at 10 mg/mL in deionized water, pH range 5.0-7.0
• Storage Stability: Less than 2% degradation over 24 months when stored at -20°C in lyophilized form

Industry data from the Peptide Therapeutics Foundation indicates that over 85% of commercial peptide failures in cosmetic applications result from inadequate purity specifications, with copper peptide degradation products causing formulation instability and reduced biological activity.

Manufacturing & Quality Control

The production of high-purity GHK-Cu copper peptide requires sophisticated manufacturing processes and rigorous quality control protocols. Understanding these procedures helps buyers evaluate supplier capabilities and ensure consistent raw material quality for their applications.

Production Process Overview

The manufacturing begins with solid-phase peptide synthesis (SPPS) using Fmoc chemistry to assemble the tripeptide sequence. After cleavage from the resin, the crude peptide undergoes purification through preparative high-performance liquid chromatography (HPLC). The copper complexation step involves controlled addition of copper chloride or copper sulfate under specific pH conditions to ensure complete coordination. Final lyophilization produces the stable powder form suitable for commercial distribution.

Quality Control and Testing Protocols

Each batch of GHK-Cu copper peptide must pass multiple analytical tests before release. The quality control process includes HPLC purity analysis with UV detection at 220 nm and 280 nm, mass spectrometry for molecular weight confirmation, and inductively coupled plasma mass spectrometry (ICP-MS) for precise copper quantification. Additional tests include residual solvent analysis, endotoxin testing, and microbial limits testing according to USP standards.

Certification and Documentation Requirements

Professional buyers should expect comprehensive documentation with each shipment. The following certifications demonstrate supplier commitment to quality:

• Certificate of Analysis (COA): Detailed purity, copper content, and specification data for each batch
• HPLC Chromatogram: Visual documentation of purity profile with peak identification
• Mass Spectrometry Report: Confirmation of molecular weight and structural integrity
• Heavy Metal Analysis: ICP-MS results showing compliance with ICH Q3D guidelines
