Quality Control

Our Benzene-1,2-Diol is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. The product is tested against rigorous in-house specifications, which typically include assay, identification, and impurity profile analysis. Certificates of Analysis (COA) documenting these results are available for every batch upon request, providing full traceability and compliance assurance for your quality protocols.

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 of being easily oxidized, it is recommended to store under an inert atmosphere such as nitrogen for long-term preservation. Keep away from strong oxidizing agents, strong acids, and strong bases.
