Description

2,2',3,4',5-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 the detection, quantification, and study of persistent organic pollutants (POPs) in various matrices.

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for calibrating analytical instruments like GC-MS and HPLC in the detection of PCBs in soil, water, and sediment samples.
• Toxicological and Biomedical Research: Serves as a key analyte in studies investigating the metabolism, bioaccumulation, and health effects of specific PCB congeners.
• Food and Feed Safety Testing: Employed as an analytical standard in laboratories to ensure compliance with regulatory limits for PCB contamination in the food chain.
• Waste and Industrial Effluent Monitoring: Acts as a standard for identifying and quantifying PCB congeners in industrial waste streams and remediation projects.
• Method Development and Validation: Critical for developing, optimizing, and validating new analytical methods for persistent organic pollutant analysis.
• Quality Control/Quality Assurance (QC/QA): Used in laboratory proficiency testing and internal quality control programs to ensure accuracy and precision in PCB analysis.
