Peptide API

Professional Peptide API Manufacturing: High-Purity Solutions for Global Pharma & Biotech

As a premier peptide API manufacturer, we provide high-purity peptide active pharmaceutical ingredients (APIs) designed for pharmaceutical companies, biotechnology firms, research organizations, and global distributors. Our operations are strictly aligned with ISO-certified quality management systems and ICH Q7 guidelines, ensuring technical reproducibility, supply chain transparency, and scalable bulk procurement.
From early-stage research to commercial-scale pharmaceutical production, our Peptide API solutions are engineered to mitigate supply risks and maintain consistent performance.

High-Purity Peptide API with Validated Quality Control

We achieve consistent purity through validated RP-HPLC (Reversed-Phase High-Performance Liquid Chromatography) protocols, meeting the most rigorous clinical standards.

Purity Specifications: Standard purity ≥98% (HPLC), with custom options up to 99%+ for sensitive clinical and high-throughput screening.

Comprehensive Quality Verification: Each batch includes a full analytical package:
Identity: LC-MS or MALDI-TOF molecular weight confirmation.
Purity: HPLC chromatograms and profile analysis.
Safety: Residual solvent testing (ICH Q3C compliant), water content analysis, and microbial/endotoxin testing.
