Description

2,2',3,3',4,4',5',6-Octachlorobiphenyl is a specific, high-purity congener of polychlorinated biphenyls (PCBs), a well-studied class of synthetic organic chemicals. This compound is of significant value for analytical and research purposes, serving as a critical reference standard for environmental monitoring and toxicological studies. It is primarily required by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutant (POP) analysis, regulatory compliance, and method development.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for the calibration of analytical instruments like GC-MS and HPLC.
• Environmental Analysis: Quantification and confirmation of PCB congeners in soil, water, sediment, and air samples for environmental impact assessments.
• Food and Feed Safety Testing: Used in methods to detect and measure PCB residues to ensure compliance with international food safety regulations.
• Toxicological Research: Serves as a precise congener standard in studies investigating the metabolism, distribution, and health effects of PCBs.
• Method Development and Validation: Essential for developing, optimizing, and validating new analytical protocols for PCB detection and quantification.
• Quality Control/Quality Assurance (QC/QA): Employed in laboratory proficiency testing and as a spike for recovery studies to ensure analytical data integrity.
• Regulatory Compliance: Supports testing mandated by regulations such as the Stockholm Convention on POPs, EPA methods, and EU directives.
