Quality Control

Our 5-Chloro-4-Hydroxycatechol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity determination and spectroscopic methods for structural confirmation, to ensure it meets the high standards required for advanced synthetic applications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and consistency.

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 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 flames.
