When exploring the world of synthetic biology and advanced cosmetic chemistry, the tripeptide stands out as a foundati 98%min Peptide content 80%min Moisture content 5% max Acetic acid content 15%max Storage -20 degrees Celsius away from light Application used as the cosmetic onal building block. A tripeptide is defined as a molecule composed of three amino acids linked by two or three peptide bonds. For those of us who track these compounds for research or formulation purposes, the CAS number serves as the primary, verifiable identifier for quality control and material sourcing Tripeptide 32 | CAS No. 1185583-20-3 .
Why CAS Number Verification Matters
The CAS number (Chemical Abstracts Service) is essential for distinguishing between specific synthetic variants. Because the chemical industry relies on precision, knowing the exact CAS No ensures that the molecular structure—such as the sequence of glycine, histidine, and lysine in Tripeptide-1—is accurate.
In my experience sourcing materials, I have found that documentation is crucial. Whether I am looking at CAS #: 147732-56-7 for Palmitoyl Tripeptide-1 or the specific Cas No. 1185583-20-3 associated with Tripeptide-32, having the correct registration number allow Tripeptide-32 s for consistent results i Tripeptide-1 · Cas No.: 72957-37-0 · Chemical Name: Gly-His-Lys acetate salt · Synonyms: · SMILES: · Formula: · M. · Purity: · Sotrage: n laboratory or personal experimentation settings.
Notable Tripeptide Profiles and Variations
Through my review of various technical data sheets, several compounds frequently appear due to their specific structural advantages:
* Palmitoyl Tripeptide-1 (CAS Number: 147732-56-7): Often identified as a type I collagen fragment, this molecule is widely recognized for its role in supporting structural integrity. It is essentially the reaction product of palmitic acid and Tripeptide-1.
* Tripeptide-1 (CAS #: 72957-37-0): Known as Tripeptide 32 | CAS No. 1185583-20-3 a multi-peptide, this is a sequence of Gly-His-Lys. It is a staple in high-end formulations for its specialized profile.
* Tripeptide-32 (Cas No. 1185583-20-3): This compound, with a molecular formula of C12H22N4O, is frequently sought for its unique properties in advanced applications. It is distinct from other sequences like CAS 1218902-80-7 Palmitoyl-tripeptide-1 (Palmitoyl Tripeptide-29).
* Tripeptide-29 (CAS #: 2239-67-0): Often referred to as collagen tripeptide, its sequence is H-Gly-Pro-Hyp-OH. It is a prime example of how specific amino acid sequences define the utility of the peptide.
Navigating Technical Specifications
When you explore CAS information, you are looking for more than just a number. You are evaluating purity, molecular weight, and storage requirements. For instance, Palmitoyl Tripeptide-1 is typically stored at -20 degrees Celsius to maintain stability.
I have found that when researching Tripeptide-32 for skincare and anti-aging applications, the purity levels—often required to be above 95%—are the most critical factor for success. Discrepancies in the CAS, 1186040-97-0 vs. the primary CAS, 1185583-20-3 can lead to confusion, so always cross-reference the manufacturer’s certificate of analysis.
Practical Considerations for Enthusiasts
Whether you are working with Tripeptide-3 or the more complex tripeptide structures like Tri-aspartic acid (CAS No. 107208-63-9), the key is attention to detail.
1. Always verify the sequence: The biological function is dictated by the specific am PalMitoyl Tripeptide-1 | Cas# 147732-56-7 ino acid order.
2. Storage: Most of these synthetic molecules are sensitive to light and temperature. Always adhere to the storage guidelines associated with the specific CAS number.
3. Documentation: Keep a log of the CAS # for every batch you use. This practice is vital for maintaining a reliable record of your personal projects.
By focusing on the verified identity of these molecules—from the widely used Palmitoyl Tripeptide-1 to the highly specific Tripeptide-32—we can better understand the potential of these incredible building blocks in our own investigations. Always ensure your sources provide transparent CAS documentation to ensure the integrity of your work.
