When exploring advanced skincare ingredients, I often find myself diving deep into the technical specifications of specific compounds. One molecule that freque Molecular Formula. C35H62N14O11S ; Synonyms. Acetyl hexapeptide-3; Acetyl Hexapeptide-8; Argireline NP; Hexapeptide 3; L4EL31FWIL ; Molecular Weight. 887.0 g/mol. ntly appears in discussions regarding anti-aging formulations is Acetyl Hexapeptide-8. Acetyl Hexapeptide-8 Cas 616204-22-9 As someone who values understanding the "why" behind product performance, I have spent considerable time researching the structural properties of this peptide, particularly its molecular weight.
Defining the Molecule: Acetyl Hexapeptide-8
Often referred Argireline (Acetyl hexapeptide-3) | Antiwrinkle Peptide to by the brand name Argireline, Acetyl Hexapeptide-8 is a synthetic peptide composed of six amino acids: Acetyl-glutamic acid, glutamic acid, methionine, glutamine, arginine, and arginine (Ac-EEMQRR-NH2). In my experience reviewing various suppliers and research documents, it is consistently identified as a white to off-white powder. Its chemic Acetyl Hexapeptide-8 616204-22-9 - Sinoway al identity is formally classified under CAS 616204-22-9.
Analyzing the Molecular Weight
The molecular weight of this compound is a critical metric for those of us interested in how peptides interact with the skin barrier. Throughout my review of technical data sheets and scientific literature, the consensus for the m Acetyl hexapeptide-8 olecular weight of Acetyl Hexapeptide-8 is consistently cited as approximately 888.99 g/mol (sometimes rounded to 889.0 Da or 889.98 Da in specific studies).
While some older or variant data might show slight deviations—such as 887.0 g/mol or specific mass calculations like 888.42358458 g/mol—the value of 889.0 remains the industry standard for this hexapeptide. It is important to distinguish this from other peptide chains; for instance, I have encountered data for other peptides with a molecular weight of 3751.20, which highlights why one must be precise when verifying purity and identity.
Structural Characteristics and Considerations
The molecular formula for this specific acetyl hexapeptide-8 is widely documented as C34H60N14O12S. Its physical behavior is largely defined by this size and its chemical structure:
* Hydrophilicity: The peptide is known for being highly water-soluble due to its polar amino acid composition.
* Permeability: Because of its relatively large molecular weight (approx. 888.99), it faces challenges Acetyl Hexapeptide-8 (Argireline®): A Potent Anti-Wrinkle in penetrating the lipid-rich stratum corneum. This is a common topic in academic reviews, which often note that this size and hydrophilic nature pose barriers to transdermal delivery.
* Stability: In my personal storage practices, I have found that keeping it in a cool, dry environment—preferably at 2–8°C—is essential for maintaining the stability of the acetyl hexapeptide-8 powder.
Practical Observations
When I source Acetyl Hexapeptide-8 for my personal research projects, I prioritize certificates of analysis that specify the 889.0 Da range. Observing the molecular weight allows me to better understand the formulation requirements. Sinc Acetyl hexapeptide-3 | C35H62N14O11S | CID 71587772 e it is a hexapeptide with a specific molecular formula, it requires careful handling to ensure it remains effective in a final solution.
Whether you are looking into Acetyl Hexapeptide-8 products for their molecular profile or simply curious about the science behind the acetyl hexapeptide-8 label, understanding these fundamental constants—888.992 or 889.0—provides a clear picture of the substance. It is a fascinating example of how a specific sequence of amino acids, when synthesized correctly, results in a distinct molecular weight that dictates its behavior in any given application.
By grounding my knowledge in these verifiable metrics, I can better evaluate the quality and potential of the acetyl hexapeptide-8 I encounter in the marketplace. As with any sophisticated chemical component, the value lies in the precision of the molecular data and the consistent quality of the raw material.
