1. Excellent Product Quality
Product quality is the cornerstone of our business. Our peptide compounds are synthesized using Solid-Phase Peptide Synthesis (SPPS), purified via High-Performance Liquid Chromatography (HPLC), and verified by Mass Spectrometry (MS).
Each batch comes with a Certificate of Analysis (COA) containing key data such as: • Purity (HPLC) • Molecular Weight (MS) • Moisture Content • Residual Solvents • Microbial Limits (where applicable).
For customers with stricter regulatory requirements, we can also provide third-party test reports, endotoxin (LAL) data, and stability study documentation upon request.
2. Custom Services and R&D Support
We offer flexible custom synthesis services backed by an experienced R&D team. Whether you require new peptide sequences, cosmetic-grade purity, or modified molecules (such as PEGylation or acetylation), we can deliver high-quality products on schedule. Our services include: • Custom peptide synthesis (milligram to kilogram scale) • Peptide modification and labeling • Small molecule synthesis • Project-based R&D and large-scale production.
We work closely with clients to ensure technical feasibility, rapid delivery, and cost control throughout the entire development cycle.
