Quality Control

Our 3,4,6-Trichlorocatechol is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatography and spectroscopy, to confirm identity and purity. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We adhere to cGMP principles where applicable to meet the stringent requirements of our pharmaceutical and research customers.

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 nature as an easily oxidized compound, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flames.
