Quality Control

Our Duroquinol is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR spectroscopy, to ensure it meets exacting specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment. We adhere to cGMP principles where applicable to guarantee consistent quality and traceability for our global B2B clients.

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 nature as an easily oxidized compound, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation to maintain optimal purity and efficacy. Keep away from strong oxidizing agents.
