Description

2,3,3',4,4'-Pentachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is of significant importance for analytical and research purposes, particularly in environmental monitoring, toxicology studies, and the calibration of detection equipment. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutant (POP) analysis and regulatory compliance.

Application

• Analytical Reference Standard: Used as a certified reference material (CRM) for the qualitative and quantitative analysis of PCB congeners in environmental samples via GC-MS or HPLC.
• Environmental Monitoring: Critical for calibrating instruments and validating methods in the testing of soil, water, sediment, and biota for PCB contamination as per EPA and other international guidelines.
• Toxicological Research: Serves as a key material in studies investigating the metabolism, environmental fate, and specific toxic effects (e.g., dioxin-like toxicity) of PCB congeners.
• Quality Control & Assurance: Employed in laboratory proficiency testing and internal quality control programs to ensure accuracy and reliability in PCB analysis.
• Regulatory Compliance Testing: Essential for laboratories performing testing to comply with regulations such as the Stockholm Convention, TSCA, and REACH concerning POPs.
• Method Development: Used by researchers and method developers to establish, optimize, and standardize new analytical techniques for halogenated organic compounds.
