Target Keyword: 5 amino peptide
Core Molecular Specs & Technical Index
The 5 amino peptide is a synthetic oligopeptide composed of five specific amino acid residues, designed for high-purity cosmetic and laboratory applications. This molecule is characterized by a molecular weight typically ranging from 500 to 700 Da, ensuring optimal skin penetration and stability in formulation. The core value for B2B buyers—including cosmetic ingredient distributors, contract manufacturers, and research labs—lies in its consistent batch-to-batch purity and defined sequence integrity.
Basic properties include a white to off-white lyophilized powder form, with solubility exceeding 10 mg/mL in deionized water at 25°C. The peptide is stable at pH 5.0–7.0 and requires storage at -20°C for long-term preservation. Purity specifications are verified via HPLC analysis, with a minimum threshold of 98% for standard grades and 99.5% for research-grade material.
- Purity Grade: Standard (≥98%) and Research (≥99.5%) by HPLC area normalization.
- Molecular Weight: 550–650 Da, confirmed by mass spectrometry (ESI-MS).
- Solubility: ≥10 mg/mL in water; ≥20 mg/mL in DMSO for lab reconstitution.
- Storage Stability: 24 months at -20°C; 12 months at 2–8°C after reconstitution.
- Endotoxin Level: <1 EU/mg for injectable-grade applications.
Industry data from the Peptide Therapeutics Foundation indicates that 5 amino peptide sequences with purity above 98% achieve 95% stability in aqueous formulations over 6 months, compared to 70% for lower-grade variants.
Manufacturing & Quality Control
The manufacturing process for 5 amino peptide begins with solid-phase peptide synthesis (SPPS) using Fmoc chemistry, ensuring precise amino acid coupling. Each cycle includes deprotection, activation, and coupling steps, monitored by Kaiser test for completion. After cleavage from the resin, the crude peptide undergoes preparative HPLC purification to remove truncated sequences and by-products.
Quality control involves a multi-tiered verification system. Each batch is tested for identity via amino acid analysis and mass spectrometry, purity by analytical HPLC, and quantity by UV spectrophotometry. Third-party testing from ISO 17025 accredited labs provides independent confirmation of specifications. Certifications include:
- COA (Certificate of Analysis): Includes HPLC chromatogram, MS spectrum, and residual solvent data.
- MSDS (Material Safety Data Sheet): Compliant with GHS standards for shipping and handling.
- GMP Compliance: Manufacturing follows current Good Manufacturing Practices for cosmetic ingredients.
- Heavy Metal Testing: ICP-MS analysis ensures lead, arsenic, cadmium, and mercury below 1 ppm.
- Microbiological Testing: Total aerobic microbial count <100 CFU/g, yeast and mold <10 CFU/g.
Commercial Application Scenarios
In cosmetic formulation, 5 amino peptide is incorporated into serums, creams, and masks at concentrations of 0.5–2.0% by weight. Its small molecular size allows efficient delivery into the epidermal layers, supporting collagen synthesis and skin firmness. Formulators value its compatibility with water-based systems and stability in pH-balanced emulsions.
For laboratory research, this peptide serves as a model compound in cell culture studies examining fibroblast activity and extracellular matrix remodeling. Researchers use it at 10–100 µM concentrations in DMEM or PBS, with viability assays confirming no cytotoxicity at these levels. Bulk wholesale buyers, such as raw material distributors, purchase 5 amino peptide in kilogram quantities for resale to cosmetic manufacturers. Typical packaging includes 1 kg, 5 kg, and 10 kg vacuum-sealed aluminum bags with desiccant.

Bulk Purchase Selection Guide
When sourcing 5 amino peptide in bulk, buyers must avoid common pitfalls such as accepting incomplete documentation or relying on verbal purity claims. Always request a full COA with HPLC and MS data for each batch. Verify that the supplier provides third-party test results from an accredited lab, not just in-house analysis.
Selection standards include checking the peptide's appearance (white powder, no discoloration), solubility in water (clear solution), and pH of a 1% solution (5.0–7.0). For cosmetic use, ensure the supplier follows GMP guidelines and provides a stability study for the specific formulation. Buyer checklist:
- Request batch-specific COA with HPLC and MS data.
- Confirm third-party testing from ISO 17025 lab.
- Verify storage conditions and shipping temperature logs.
- Check for heavy metal and microbial test results.
- Ask for formulation compatibility data if needed.
Core Product Advantages
