Description

2,2',3,3',4,5-Hexachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is of significant interest for research, analytical, and regulatory compliance purposes due to its role as a persistent environmental contaminant. It is primarily required by environmental testing laboratories, chemical reference standard producers, and academic institutions conducting toxicological and environmental fate studies.

Application

• Analytical Reference Standard: Used as a certified standard for the calibration and validation of analytical instruments like GC-MS and HPLC in environmental testing.
• Environmental Research: Serves as a model compound in studies investigating the degradation, bioaccumulation, and long-range transport of PCBs in ecosystems.
• Toxicology Studies: Employed in laboratory research to understand the specific toxicological profile, metabolic pathways, and health effects of this PCB congener.
• Method Development: Utilized by laboratories to develop and refine analytical methods for the detection and quantification of PCBs in complex matrices such as soil, water, and biological tissues.
• Quality Control/Quality Assurance (QC/QA): Acts as a spike or control material in laboratory QC protocols to ensure accuracy and precision in PCB analysis for regulatory compliance.
• Regulatory Compliance Testing: Essential for laboratories performing testing to comply with global regulations (e.g., Stockholm Convention, EPA methods) governing PCB monitoring and remediation.
