When exploring the world of advanced cosmetic ingredients, one name frequently surfaces: Copper Tripeptide-1. As someone who spends considerable time researching the technical specifications of skincare actives, I have found that navigating the nomencla GS-PepRejuv™ Copper Tripeptide-1, Hydrochlorate ture—specifically the CAS Number—is essential for ensuring ingredient quality and authenticity.
Deciphering the Identity: Copper Tripeptide CAS No.
The most recognized identifier for this complex is CAS No. 89030-95-5. This specific code is the industry standard for identifying Copper Tripeptide-1, a peptide complex often described as a "blue copper peptide" due to its distinct coloration. In my experience, seeing this CAS Number on a Certificate of Analysis (COA) is a primary indicator that the manufacturer is utilizing the globally recognized form of the material.
However, the landscape of peptide chemistry is nuanced. You will often encounter other Prezatide copper - CID 71587328 - PubChem - NIH identifiers, such as CAS Number 49557-75-7, which is frequently associated with the broader category of Copper Peptide (GHK-Cu). For those deep into the technical literature, you may also see references to CAS No. 130120-57-9 or even CAS No. 300801-03-0, which often relates to specific acetate salt forms of the peptide, such as Copper tripeptide-1.xHOAc (FC180071) Cas No: 89030-95.
The Science Behind the Complex
Copper tripeptide is a fascinating subject because it is a naturally occurring metabolite. It was is first isolated from human plasma, and it is also found in trace amounts in saliva and urine. The molecule is essentially a complex of the tripeptide glycyl-L-histidyl-L-lysine bound with a copper ion.
From a formulation perspective, the molecular weight is a critical parameter. Most technical specifications list the molecular weight at approximately 401.91 g/mol. Whether you are looking at Copper Tripeptide-1 Liquid or a high-purity lyophil Copper tripeptide-1.xHOAc, 5 g ized powder, the goal is always to maintain stability. I always check for the CAS to ensure I am not confusing it with CAS Number, 767286-83-9, which refers to Copper tripeptide-3 (AHK-Cu), a different bioactive peptide entirely.
Personal Observations on Formulation and Quality
When sourcing these materials, the CAS NO. · 89030-95-5 serves as my north star. I have learned that the purity of the Copper Peptide is paramount. A high-quality batch should present as a fine blue to purple crystalline powder. If you are comparing products, remember that Copper tripeptide is highly sensitive to environmental factors, which is w What is Copper Tripeptide-1? | Paula's Choice hy proper storage—often at -20°C—is recommended by suppliers.
Whether you are a formulator or an enthusiast, here is a quick checklist for verifying your ingredients:
* Verification: Always cross-reference the Cas No provided by the supplier with the official chemical database records (like PubChem or ECHA).
* Consistency: Note that Tripeptide-1 Copper/Blue Copper Peptide CAS No. 89030-95-5 refers to the specific tripeptide structure, whereas CAS Number 49557-75-7 is often used for the general GHK-Cu complex.
* Purity: Look for batch reports that specify the CAS: 89030-95-5 alongside purity levels, which should ideally exceed 98-99%.
