Description

Polychlorinated Biphenyl (Kanechlor 500) is a specific, high-chlorine congener mixture within the polychlorinated biphenyl (PCB) family, known for its historical use as a stable dielectric fluid and heat transfer medium. Its primary commercial value lies in its exceptional chemical inertness and thermal stability under demanding industrial conditions. This product is essential for specialized industrial applications, including research into environmental remediation, analytical standard preparation, and controlled material science studies.

Application

• Primary use as a dielectric insulating fluid in specialized capacitors and transformers for research and development purposes.
• Employed as a heat transfer fluid in closed-loop experimental systems requiring high thermal stability.
• Critical reference standard and analytical reagent for environmental testing laboratories to calibrate equipment and quantify PCB contamination.
• Used in material science research as a plasticizer and flame retardant additive for studying historical polymer formulations.
• Component in hydraulic and lubricating fluids for legacy machinery maintenance under strict regulatory oversight.
• Essential for scientific research on PCB degradation, environmental fate, and remediation technologies.

Quality Control

Our Polychlorinated Biphenyl (Kanechlor 500) is produced and handled under stringent controls to ensure batch-to-batch consistency and identity for research applications. Each lot is analyzed to confirm congener distribution profile and purity. A comprehensive Certificate of Analysis (COA) detailing congener-specific data via GC-MS or HPLC is provided to support regulatory compliance and research integrity. All materials are managed in accordance with global chemical control regulations, including Stockholm Convention guidelines for permitted use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from strong acids and organic solvents. Recommended storage temperature is 2-25°C. Due to the persistent and bioaccumulative nature of PCBs, ensure containers are clearly labeled and stored in a dedicated, secure area to prevent cross-contamination.
