Quality Control

Our 4-Hydroxy-2',3,3',4',5,5'-Hexachlorobiphenyl is produced and handled under strict quality protocols to ensure batch-to-batch consistency and high purity, essential for reliable analytical results. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity confirmation, and impurity profiles. Our quality systems are designed to meet the rigorous demands of research and analytical reference standard applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere for long-term stability. Keep away from strong oxidizing agents.
