GHK-Cu Peptide Raw Material Factory CAS 49557-75-7 99% Purity

GHK-Cu Peptide Raw Material Factory CAS 49557-75-7 99 Percent Purity When sourcing raw materials for research and development, the purity and consistency of the chemical compound are non-negotiable. The GHK-Cu peptide, also known as copper peptide or copper tripeptide-1, is a complex formed by the tripeptide glycyl-histidyl-lysine and a copper ion. With a CAS number of 49557-75-7, this compound is widely studied for its role in cellular processes. Our factory specializes in the production of GHK-Cu peptide raw material, delivering a guaranteed 99 percent purity verified by high-performance liquid chromatography analysis. This article provides a detailed, objective examination of the product parameters, chemical properties, quality certifications, and practical considerations for buyers. Product Parameters and Chemical Composition The GHK-Cu peptide is a coordination complex where the copper ion is bound to the tripeptide sequence. The molecular formula is C14H24N6O4Cu, with a molecular weight of approximately 403.93 g/mol. The compound appears as a light blue to blue powder, which is characteristic of copper-containing peptides. The 99 percent purity level is critical because it ensures that the active peptide complex is present in a consistent concentration, minimizing the presence of unreacted amino acids, copper salts, or other byproducts. Our factory uses a controlled synthesis process that begins with high-quality amino acids and copper sulfate, followed by purification steps including crystallization and lyophilization. Each batch is subjected to HPLC analysis to confirm the purity and to quantify the copper content, which typically falls within a narrow range of 15.5 to 16.5 percent by weight. This precise composition supports reproducible results in laboratory settings. Quality Certifications and Data Comparison Our facility holds ISO 9001 and Good Manufacturing Practice certifications, which are internationally recognized standards for quality management and production consistency. These certifications require rigorous documentation of all processes, from raw material intake to final packaging. For each batch of GHK-Cu peptide, we provide a Certificate of Analysis and a Material Safety Data Sheet. The COA includes detailed results from HPLC, heavy metal analysis, and residual solvent testing. Compared to lower-purity alternatives often found in the market, our product demonstrates significantly lower levels of heavy metal residues, such as lead, arsenic, and cadmium, which are typically below 10 parts per million. Many suppliers offer GHK-Cu peptide with purity levels between 95 and 98 percent, which can contain higher levels of copper oxide or unbound copper. These impurities can interfere with experimental outcomes, leading to variable bioactivity. Our 99 percent purity standard ensures that the peptide complex is intact and that the copper ion is properly chelated, which is essential for its stability and function. The GMP certification also guarantees that the production environment is controlled for temperature, humidity, and particulate contamination, further reducing the risk of degradation. Brand Advantages and Limitations The primary advantage of sourcing GHK-Cu peptide from our factory is the combination of high purity and full traceability. Each batch is assigned a unique lot number, and all documentation, including the COA and MSDS, is available for review. This transparency allows researchers to verify the quality before use. Additionally, we offer competitive bulk pricing for larger quantities, which is beneficial for laboratories conducting extensive studies or for companies requiring consistent supply. The product is packaged in double-sealed, light-protected containers to minimize exposure to moisture and air. However, there are limitations to consider. The GHK-Cu peptide is moisture-sensitive and requires storage in a desiccated environment at temperatures between 2 and 8 degrees Celsius. Exposure to humidity can cause the powder to clump or degrade, reducing its effectiveness. The compound is also sensitive to light, so it must be stored in opaque containers or in a dark cabinet. These storage conditions are standard for peptide raw materials but require careful attention from the buyer. Customer Selection Tips and Precautions For buyers evaluating GHK-Cu peptide suppliers, several factors should be considered to ensure product quality. First, always request a third-party lab report that includes HPLC analysis and heavy metal testing. A reputable supplier will provide this documentation without hesitation. Second, verify the traceability of the raw materials. Ask for the batch number and check if the supplier can provide a complete chain of custody from the amino acid source to the final product. Third, request a free sample for stability testing. A small sample can be subjected to accelerated stability studies, such as exposure to elevated temperature or humidity, to see how the product behaves over time. Avoid suppliers who cannot provide full documentation or who offer prices significantly lower than the market average, as this often indicates lower purity or adulteration. When handling the powder, use a glove box or a dry nitrogen environment to prevent moisture absorption. Always reseal the container immediately after use and store it in a refrigerator. For long-term storage, consider using a vacuum desiccator. Frequently Asked Questions What is the difference between GHK-Cu peptide and other copper peptides? GHK-Cu peptide is a specific complex of the tripeptide glycyl-histidyl-lysine with a single copper ion. Other copper peptides may use different peptide sequences or have different copper binding ratios. The purity and composition of GHK-Cu are well-defined, making it a standard reference compound for research. The CAS number 49557-75-7 uniquely identifies this specific complex. How should I verify the purity of the GHK-Cu peptide I receive? The most reliable method is to request a Certificate of Analysis from the supplier that includes HPLC chromatogram data. You can also send a sample to an independent laboratory for confirmation. The HPLC method should show a single major peak with a retention time consistent with the standard. The copper content can be verified by inductively coupled plasma mass spectrometry. Can I use GHK-Cu peptide in cell culture experiments? Yes, GHK-Cu peptide is commonly used in cell culture studies to investigate cellular processes such as proliferation and migration. However, it is important to dissolve the powder in a suitable solvent, such as sterile water or phosphate-buffered saline, and to filter the solution through a 0.22 micron filter to ensure sterility. The concentration used will depend on the specific experimental design, and a dose-response curve is recommended to determine the optimal range.
