Core Molecular Specs & Technical Index
The aod peptide (Adipotide) is a synthetic peptide composed of 10 amino acids, designed for targeted binding to specific cellular receptors. For B2B buyers in cosmetic formulation and laboratory research, understanding the precise molecular specifications is critical for ensuring batch-to-batch consistency and functional performance. The peptide sequence is CKGGRAKDC-NH2, with a molecular weight of approximately 1122.3 Da. High-purity aod peptide is supplied as a lyophilized white powder, free from visible particulates or discoloration.
- Purity Level: Minimum 98% by HPLC analysis, with premium grades reaching 99.5% for research applications.
- Solubility Profile: Readily soluble in sterile water, PBS, or DMSO at concentrations up to 10 mg/mL for formulation flexibility.
- Storage Stability: Lyophilized powder stable for 24 months at -20°C; reconstituted solutions stable for 7 days at 2-8°C.
- Endotoxin Content: Less than 1 EU/mg for cosmetic-grade material; less than 0.1 EU/mg for laboratory-grade material.
- Peptide Content: Typically 70-80% net peptide content by weight, with the remainder being counterions and water.
Industry data indicates that over 85% of peptide-related formulation failures in cosmetic R&D are traced to raw material purity below 95% or incorrect storage protocols. Sourcing aod peptide with verified HPLC certificates reduces batch rejection rates by 40%.
Manufacturing & Quality Control
The production of aod peptide follows a rigorous solid-phase peptide synthesis (SPPS) process using Fmoc chemistry. Each amino acid is sequentially coupled to a resin support, with real-time monitoring of coupling efficiency via Kaiser test. After cleavage and deprotection, the crude peptide undergoes preparative HPLC purification to achieve the target purity grade. Quality control includes mass spectrometry (MS) for molecular weight confirmation and analytical HPLC for purity verification.
- Production Process: Automated SPPS with 99.5% coupling efficiency per cycle, minimizing deletion sequences.
- Purification Method: Reverse-phase preparative HPLC using C18 columns with gradient elution for sharp peak separation.
- Third-Party Testing: Independent laboratory analysis for heavy metals, residual solvents, and microbial limits per USP standards.
- Certification List: Certificate of Analysis (CoA), Mass Spec report, HPLC chromatogram, and MSDS provided with each batch.
- Batch Traceability: Unique lot numbers enable full traceability from raw material sourcing to final packaging.
Commercial Application Scenarios
The aod peptide serves distinct roles across cosmetic formulation and laboratory research sectors. In cosmetic applications, it is incorporated into topical serums and creams at concentrations between 0.1% and 1.0%, where its molecular properties support targeted delivery systems. For laboratory research, the peptide is used in cell culture studies and receptor binding assays at micromolar concentrations, requiring consistent purity for reproducible results.
- Cosmetic Formulation: Used in anti-aging serums and targeted delivery creams, where aod peptide enhances ingredient penetration and cellular interaction.
- Lab Research: Applied in receptor binding studies and cellular uptake assays, with purity above 99% essential for accurate data.
- Bulk Wholesale: Supplied in 1g, 5g, and 10g quantities for large-scale formulation development and commercial production.
- Custom Synthesis: Modified sequences or labeling (e.g., biotin, FITC) available for specialized research requirements.

Bulk Purchase Selection Guide
When sourcing aod peptide in bulk quantities, buyers must evaluate several critical factors to avoid common pitfalls. The peptide market includes variable quality grades, and selecting the wrong specification can lead to formulation failures or research data inconsistencies. A systematic approach to supplier evaluation and material verification ensures cost-effective procurement.
- Common Pitfalls: Accepting purity claims without HPLC chromatograms, ignoring endotoxin levels for cell work, and failing to verify storage conditions during shipping.
- Selection Standards: Require third-party HPLC and MS reports for each batch, confirm endotoxin levels match your application, and request stability data for your intended storage conditions.
- Buyer Checklist: Verify supplier ISO 9001 certification, request batch-specific CoA, confirm peptide content percentage, check solubility in your target solvent, and review shipping temperature requirements.
- Cost Consideration: Higher purity grades command premium pricing, but reduce waste and rework costs in formulation development by up to 30%.

- Stability Optimization: Lyophilization parameters are optimized for each batch to maintain peptide structure and prevent aggregation during long-term storage.
- Cost Performance: Direct manufacturing relationships eliminate intermediary markups, providing competitive pricing without compromising quality standards.
- Technical Support: Dedicated peptide specialists provide formulation guidance, solubility optimization, and troubleshooting for integration into complex cosmetic matrices.
Frequently Asked Questions
Q1: What is the minimum purity required for cosmetic formulation use of aod peptide?
For cosmetic applications, a minimum purity of 98% by HPLC is recommended. This ensures that the peptide functions as intended without interference from truncated sequences or side products that could affect formulation stability or sensory properties. Premium formulations may benefit from 99%+ purity for enhanced consistency.
Q2: How should aod peptide be stored to maintain stability during bulk storage?
Lyophilized aod peptide should be stored at -20°C in a desiccated environment, protected from light. For bulk quantities, aliquot the powder into single-use vials to avoid repeated freeze-thaw cycles. Under these conditions, the peptide remains stable for up to 24 months from the date of manufacture.
Q3: Can aod peptide be used in water-based cosmetic formulations without solubility issues?
Yes, aod peptide is readily soluble in water at concentrations up to 10 mg/mL. For higher concentrations or complex formulations, pre-dissolve in a small volume of sterile water or PBS before incorporating into the final formulation. Avoid prolonged exposure to temperatures above 25°C to maintain peptide integrity.
