In the world of skincare and laboratory research, few ingredients have garnered as much attention as the GHK-Cu complex. As someone who has spent significant time sourcing peptides for personal study and formulation, I have found that demystifying the technical specifications—particularly the copper peptide CAS number—is essential for ensuring quality and authenticity.
Why the CAS Number Matters
When you are looking for high-quality copper peptide raw materials, you will often encounter various identification codes. The CAS (Chemical Abstracts Service) Number acts as a unique digital fingerprint for a GHK-Cu 2+ [49557-75-7] - Copper Peptide chemical substance. It is the most reliable way to verify that the product you are holding is indeed the specific molecule you intended to purchase.
For GHK-Cu, which is a copper-peptide complex consisting of a tripeptide (Glycyl-L-histidyl-L-lysine) bound to a copper ion, you will frequently see two primary identifiers:
* 49557-75-7: This is the most widely cited CAS Registry Number, 49557-75-7, often associated with the base GHK-Cu structure.
* 89030-95-5: You will also see this CAS No. 89030-95-5 frequently in supplier catalogs, particularly when Prezatide copper - CID 71587328 - PubChem - NIH referring to Copper tripeptide-1.
Navigating the Technical Data
When reviewing a Certificate of Analysis (CoA) for Copper Peptide CAS 49557-75-7, it is important to look at the molecular details. The substance is a blue-to-purple powder, which is a hallmark of the copper ion interaction.
From my experience, understanding the number associated with these compounds helps in distinguishing between different salt forms, such as Prezatide copper or other acetate derivatives. For instance, CAS 130120-57-9 is another ide Copper tripeptide | CAS NO.:89030-95-5 ntifier that appears in specific cosmetic-grade formulations. Whether you are searching for CAS 89030-95-5 or CAS:49557-75, being precise ensures that you are working with the correct molecular weight and structural formula.
Application and Personal Experience
I have found that when working with Copper peptides in a DIY or experimental setting, the purity level is paramount. High-quality Copper Peptide Powder should be highly soluble and consistent in appearance.
* Identification CAS Number · 49557-75-7 · (Cu complex): 89030-95-5 ; 3D model (JSmol). Interactive image; (Cu complex): Interactive image ; ChEBI · CHEBI:95185 ; ChemSpider · 66263 : Always verify the CAS NO. · 89030-95-5 or CAS 49557-75-7 on the product label.
* Storage: These complexes are sensitive to light and temperature. I keep my samples in an airtight, opaque container to maintain stability.
* Consistency: If you are comparing sources, check if the supplier provides the CAS No. [89030-95-5] in the Prezatide copper | C14H23CuN6O4+ | CID 71587328 - structure, chemical names, physical and chemical properties, classification, patents, literature, ir safety data sheets. Transparency in these technical details is a sign of a reputable manufacturer.
Final Thoughts on Sourcing
Whether you are interested in Copper Tripeptide-1 for its role in supporting skin appearance or simply exploring the chemistry behind it, th Basic information: INCI Name: Copper Tripeptide-1(GHK-Cu) Cas No: 89030-95-5, 49557-75-7,130120-57-9. Formula: C14H24N6O4 Molecular: 340.5 e CAS system is your best tool for clarity. By focusing on the number associated with your specific peptide, you can avoid confusion in a market flooded with similar-sounding ingredients.
Always cross-reference the CAS:49557-75 or 89030-95-5 codes provided by your supplier against public chemical databases. This simple step has saved me from purchasing mislabeled products on multiple occasions, ensuring that my bench-top experiments remain consistent and reliable. Always remember that these substances are for external or research purposes only, and understanding their chemical identity is the first step toward informed usage.
