Description

2,2',3,3',4,5,5',6-Octachlorobiphenyl is a specific, high-purity congener of polychlorinated biphenyls (PCBs). This compound is of significant importance for analytical and research purposes, particularly in environmental monitoring and toxicological studies. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions for use as a certified reference material (CRM) or analytical standard to calibrate equipment and ensure accurate quantification of PCB contaminants.

Application

• Certified Reference Material (CRM) for the calibration of analytical instruments such as GC-MS and HPLC.
• Environmental Analysis Standard for the detection and quantification of PCB congeners in soil, water, and sediment samples.
• Toxicological Research to study the specific biological effects, metabolism, and persistence of individual PCB congeners.
• Quality Control/Quality Assurance (QC/QA) in laboratories to validate analytical methods for PCB determination.
• Regulatory Compliance Testing to monitor industrial emissions and waste in accordance with global environmental regulations (e.g., Stockholm Convention).
• Food and Feed Safety Analysis for screening potential PCB contamination in the food chain.
