Description

2,2',3,3',4-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 tool in environmental monitoring and toxicological research. It is essential for laboratories and research institutions focused on legacy pollutant analysis, regulatory compliance testing, and studying the environmental fate and health effects of persistent organic pollutants (POPs).

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the calibration of analytical instruments like GC-MS and HPLC in the quantification of PCB residues in soil, water, sediment, and biota.
• Toxicological and Biomedical Research: Serves as a precise congener-specific standard in studies investigating the metabolism, distribution, and toxic effects (e.g., endocrine disruption, carcinogenicity) of PCBs.
• Regulatory Compliance and Method Validation: Essential for laboratories performing testing to comply with international regulations (e.g., Stockholm Convention, EPA methods) regarding POPs, ensuring accurate and legally defensible results.
• Food and Feed Safety Testing: Employed as an analytical standard to detect and quantify PCB contamination in food chains, supporting safety assessments for regulatory bodies and quality control labs.
• Waste and Remediation Site Characterization: Used to identify and quantify specific PCB congeners at industrial waste sites, aiding in risk assessment and monitoring the effectiveness of remediation efforts.
• Quality Control for Manufacturing: Acts as a purity standard for companies synthesizing or formulating specialized chemical products where PCB contamination must be rigorously excluded and monitored.
