Quality Control

Our 2,3,5,7-Tetrahydroxy-1,4-Naphthoquinone is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support custom synthesis and can tailor purity grades to meet specific research or industrial requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize exposure to air and moisture.
