Quality Control

Our 1,4-Naphthalenediol, 5-Amino-2,3-Dichloro- is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure high purity and consistent composition, meeting the stringent requirements for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles 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, well-ventilated area at 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 incompatible materials such as strong oxidizing agents.
