Quality Control

Our Durohydroquinone is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Production adheres to cGMP guidelines where applicable. Each lot is tested against rigorous in-house specifications, which typically include assay, identification, and impurity profile analysis via HPLC and other validated methods. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your technical 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 properties of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep away from strong oxidizers, strong bases, and incompatible materials.
