Core Molecular Specs & Technical Index
Oxytocin (C₄₃H₆₆N₁₂O₁₂S₂) is a cyclic nonapeptide with a molecular weight of 1007.19 g/mol. Its unique disulfide bridge between Cys1 and Cys6 confers exceptional conformational stability, making it a preferred candidate for high-precision research applications. The peptide is typically supplied as a lyophilized powder to maximize shelf life and minimize degradation.
- Purity: ≥98% verified by HPLC; leading manufacturers like Bachem achieve 99.5% via RP-HPLC.
- Solubility: Readily soluble in water (≥10 mg/mL) and PBS buffer (pH 7.4).
- Storage: -20°C desiccated; lyophilized form stable for 24 months.
- Endotoxin Level: <0.5 EU/mg for sterile research-grade batches.
- Counterion: Typically acetate salt (TFA-free) for optimal bioactivity.
Industry data from 2024 shows that GMP-certified oxytocin batches with ≥98% purity exhibit 40% longer stability in accelerated aging tests compared to generic-grade alternatives (source: Bachem technical bulletin).
Manufacturing & Quality Control
Production follows solid-phase peptide synthesis (SPPS) using Fmoc chemistry, followed by cleavage, oxidation, and preparative HPLC purification. Each batch undergoes rigorous third-party testing to ensure compliance with research safety standards.
- Process: Automated SPPS with real-time monitoring of coupling efficiency.
- Purification: Two-stage RP-HPLC to remove truncated sequences and oxidation byproducts.
- Third-Party Test: Independent HPLC, MS, and amino acid analysis reports provided per lot.
- Certifications: GMP, ISO 9001, and endotoxin-free certificates available upon request.
Commercial Application Scenarios
Oxytocin peptide is widely utilized across three primary sectors: cosmetic formulation, laboratory research, and bulk wholesale distribution. In cosmetics, it is incorporated into anti-aging serums at 0.1–0.5% concentration for its skin-soothing properties. In research labs, it serves as a standard for receptor binding assays and behavioral studies. Bulk buyers (≥1 kg) typically require lyophilized powder with full COA and stability data for long-term inventory management.

Frequently Asked Questions
Q1: What is the typical purity range for research-grade oxytocin peptide?
Research-grade oxytocin peptide typically ranges from 98% to 99.5% purity, verified by HPLC. Higher purity ensures minimal interference in binding assays and cell-based studies.
Q2: How should oxytocin peptide be stored to maintain stability?
Store lyophilized oxytocin peptide at -20°C in a desiccated environment. Avoid repeated freeze-thaw cycles. Reconstituted solutions should be used within 7 days when stored at 4°C.
Q3: What certifications should I look for when buying oxytocin peptide in bulk?
Request GMP certification, ISO 9001 compliance, and a Certificate of Analysis (COA) with HPLC chromatogram and endotoxin test results. Third-party testing ensures product quality and research safety.
