Description

2,2',4,4',5-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 as a reference standard for calibration. It is primarily required by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutant (POP) analysis, legacy contamination, and regulatory compliance.

Application

• Analytical Reference Standard: Used as a certified reference material (CRM) for the quantitative and qualitative analysis of PCB congeners in environmental samples via GC-MS or GC-ECD.
• Environmental Monitoring: Critical for calibrating equipment and validating methods in the testing of soil, sediment, water, and air for PCB contamination to meet regulatory standards.
• Toxicological Research: Serves as a key compound in studies investigating the bioaccumulation, metabolic pathways, and specific health effects of individual PCB congeners.
• Method Development & Validation: Essential for laboratories developing or accrediting new analytical procedures for persistent organic pollutants (POPs) under frameworks like EPA methods.
• Quality Control/Quality Assurance (QC/QA): Employed as an internal standard or spike in laboratory QC protocols to ensure accuracy and precision in PCB congener analysis.
• Forensic and Source Identification: Used in environmental forensics to help identify the source and history of PCB contamination based on congener profiles.
