Description

2,3,4',5,6-Pentachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is primarily utilized as a critical reference standard and analytical standard for environmental monitoring, toxicological research, and regulatory compliance testing. It serves industries and research institutions focused on persistent organic pollutant (POP) analysis, food safety, and environmental forensics.

Application

• Analytical Reference Standard: Primary use for the calibration of analytical instruments (GC, GC-MS, HPLC) in environmental and food testing laboratories.
• Environmental Monitoring: Used as a marker compound for the identification and quantification of PCB congeners in soil, water, sediment, and air samples.
• Toxicological Research: Serves as a key material in studies investigating the metabolism, bioaccumulation, and toxic effects of specific PCB congeners.
• Method Development & Validation: Essential for developing, optimizing, and validating analytical methods for PCB detection and quantification according to EPA, EU, and other international standards.
• Quality Control/Quality Assurance (QC/QA): Employed in laboratory proficiency testing and as an internal or external standard to ensure accuracy and precision in PCB analysis.
• Regulatory Compliance Testing: Used to verify compliance with global regulations concerning POPs, such as the Stockholm Convention.
