Quality Control

Our high-purity PCB congeners, including 2,2',3,4,4',5',6-Heptachlorobiphenyl, are produced and handled under strict quality protocols to ensure identity, purity, and stability. Each batch is analyzed using state-of-the-art chromatographic and spectroscopic techniques. A comprehensive Certificate of Analysis (COA) detailing purity, congener-specific identity confirmation, and trace solvent levels is provided with every shipment to support your research and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This material is light-sensitive and should be stored away from strong acids and organic solvents. For long-term stability, consider storage at 2-8°C.
