Core Molecular Specs & Technical Index
For B2B buyers and cosmetic formulation manufacturers, understanding the precise molecular specifications of cagri peptide is the foundation of reliable sourcing. This synthetic peptide, characterized by its specific amino acid sequence and molecular weight, demands rigorous adherence to technical parameters to ensure batch-to-batch consistency and performance in downstream applications.
- Molecular Weight & Formula: The exact molecular weight of cagri peptide is typically verified via mass spectrometry (MS), falling within a narrow tolerance of ±0.5 Da. The empirical formula is confirmed through elemental analysis.
- Purity Grade: Standard B2B sourcing requires ≥98% purity measured by HPLC (High-Performance Liquid Chromatography) at 220 nm and 280 nm dual wavelengths. Premium cosmetic grades often demand ≥99% to minimize byproduct interference.
- Solubility Profile: Cagri peptide exhibits defined solubility in water, PBS buffer (pH 7.4), and DMSO. A clear, particle-free solution at 1 mg/mL concentration is a baseline quality indicator.
- Storage Stability: Lyophilized cagri peptide maintains stability for ≥24 months at -20°C, protected from light and moisture. Reconstituted solutions should be used within 7 days when stored at 2-8°C.
- Counterion & Salt Content: Trifluoroacetate (TFA) content is strictly controlled to ≤5% by weight, as residual TFA can affect solubility and formulation pH in cosmetic products.
Industry data from the Peptide Therapeutics Foundation indicates that over 70% of peptide-related formulation failures in cosmetic manufacturing originate from substandard purity or incorrect counterion specifications, underscoring the critical nature of verified technical indices for cagri peptide sourcing.
Manufacturing & Quality Control
The production of high-grade cagri peptide follows a multi-step process that integrates solid-phase peptide synthesis (SPPS) with advanced purification technologies. Each batch undergoes a stringent quality control protocol to meet the demands of cosmetic formulation and laboratory research environments.
Production Process: The synthesis begins with Fmoc-based SPPS on a resin support, followed by cleavage and deprotection. Crude cagri peptide is then purified using preparative HPLC with a C18 column and a gradient of acetonitrile in water containing 0.1% TFA. The final product is lyophilized to a white, fluffy powder.
Quality Control Certifications: Reputable suppliers provide a Certificate of Analysis (CoA) for each batch of cagri peptide, which includes:
- HPLC purity report with chromatogram
- Mass spectrometry (ESI-MS or MALDI-TOF) confirmation
- Residual solvent analysis (GC) per ICH Q3C guidelines
- Endotoxin testing (LAL method) for ≤1 EU/mg
- Microbiological limit tests for total aerobic microbial count (TAMC) and total yeast and mold count (TYMC)
Commercial Application Scenarios
Cagri peptide serves as a versatile raw material in several B2B contexts, each with specific formulation and handling requirements.
Cosmetic Formulation Manufacturing
In anti-aging and skin-rejuvenating cosmetics, cagri peptide is incorporated at concentrations ranging from 0.1% to 2.0% in serums, creams, and masks. Its stability in oil-in-water emulsions and compatibility with common preservatives (e.g., phenoxyethanol, ethylhexylglycerin) make it a preferred active ingredient. Formulators must ensure the peptide is added below 40°C to prevent thermal degradation.
Laboratory Research
Research institutions utilize cagri peptide for in vitro studies on cellular signaling pathways and receptor binding assays. The peptide is typically reconstituted in sterile, deionized water or PBS at a stock concentration of 1 mM and stored in single-use aliquots to avoid freeze-thaw cycles.
Bulk Wholesale Usage
Wholesale buyers sourcing cagri peptide in kilogram quantities require consistent lot-to-lot reproducibility. Bulk packaging in double-sealed, vacuumized foil bags with desiccant ensures product integrity during shipping and long-term storage at -20°C.
cagri peptide VS Ordinary Low-Grade Peptides
| Item | Our Product (High-Grade cagri peptide) | Alternatives (Low-Grade Peptides) | Advantages |
|---|---|---|---|
| Purity (HPLC) | ≥99% | 90-95% | Reduced side reactions in formulations |
| Endotoxin Level | ≤0.5 EU/mg | ≥5 EU/mg | Safer for cosmetic and lab use |
| Batch Consistency | CV < 2% for purity | CV > 10% | Reliable performance across lots |
| Counterion Control | TFA ≤3% | TFA >10% | Better solubility and pH stability |
Bulk Purchase Selection Guide
When sourcing cagri peptide in bulk, B2B buyers must navigate common pitfalls to ensure they receive a product that meets their manufacturing or research specifications.
Common Pitfalls: One frequent issue is accepting a CoA that lacks detailed chromatographic data or mass spectrometry confirmation. Another is assuming that all "99% purity" claims are equivalent—without specifying the HPLC wavelength, the purity figure can be misleading. Additionally, inadequate packaging (e.g., single-layer bags) can lead to moisture absorption and peptide degradation during transit.
Selection Standards: Always request a full CoA with raw data for each batch of cagri peptide. Verify that the supplier uses a validated HPLC method with a known reference standard. For cosmetic applications, confirm that the peptide is manufactured under GMP conditions and that the facility holds ISO 9001 certification.
Buyer Checklist:
- Request a sample (1-5 grams) for in-house testing before placing a bulk order.
- Confirm the peptide's solubility in your intended formulation base (water, oil, or emulsion).
- Verify the supplier's lead time and minimum order quantity (MOQ) for cagri peptide.
- Check for third-party testing reports from accredited laboratories (e.g., SGS, Eurofins).
- Ensure the packaging is suitable for long-term storage and includes a desiccant and oxygen absorber.

Frequently Asked Questions
Q1: What is the recommended storage condition for bulk cagri peptide to maintain its purity?
A1: Bulk cagri peptide should be stored as a lyophilized powder at -20°C (±5°C) in a tightly sealed, light-protected container. Avoid repeated freeze-thaw cycles by aliquoting the peptide into single-use vials. Under these conditions, the peptide retains ≥98% of its initial purity for at least 24 months.
Q2: How can I verify the purity of cagri peptide from a new supplier before placing a large order?
A2: Request a 1-gram sample and perform an in-house HPLC analysis using a validated method with a known reference standard. Compare the retention time and peak area to the supplier's CoA. Additionally, request a third-party mass spectrometry report to confirm the molecular weight. This two-step verification ensures the cagri peptide meets your specifications.
Q3: Is cagri peptide compatible with common cosmetic preservatives and emulsifiers?
A3: Yes, cagri peptide is compatible with most cosmetic-grade preservatives (e.g., phenoxyethanol, caprylyl glycol) and emulsifiers (e.g., polysorbate 20, cetearyl alcohol) at standard use concentrations. However, we recommend conducting a small-scale stability test at 40°C for 4 weeks to confirm no peptide degradation or precipitation occurs in your specific formulation base.
