Quality Control

Our Polyprenal (13~21) is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for assay and chain length distribution, to ensure it meets precise specifications for research and industrial use. A Certificate of Analysis (COA) documenting purity, identity, and key physical parameters is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
