About Us

TNJONE specialize in the development and global distribution of high-quality research-use-only (RUO) raw materials, including peptides, small molecules, and biochemical reagents.

Our products are widely used in life science research, drug discovery, cosmetics, anti-aging medicine, and functional health industries.

1. Superior Product Quality

    Product quality is the foundation of our business. Peptides are synthesized using solid-phase peptide synthesis (SPPS), then purified through HPLC and confirmed by mass spectrometry (MS).

    Each batch includes a Certificate of Analysis (COA) with key data:
        • Purity (HPLC)
        • Molecular weight (MS)
        • Water content
        • Residual solvents
        • Microbial limit (if applicable)

    For clients with higher regulatory demands, we also provide third-party testing reports, endotoxin (LAL) data, and stability studies upon request.

2. Customization & R&D Support

    We offer flexible custom synthesis services, supported by an experienced R&D team. Whether you’re looking for novel peptide sequences, cosmetic-grade purity, or modified molecules (e.g., PEGylation, acetylation), we can deliver high-quality results on time.

    Our services include:
        • Custom peptide synthesis (mg to kg scale)
        • Peptide modifications and labeling
        • Small molecule synthesis
        • Project-based research and scale-up

    We work closely with our clients to ensure technical feasibility, fast delivery, and cost control throughout the development cycle.
