Description

2,3,3',4,5'-Pentachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is of significant interest for analytical and research purposes, particularly in environmental monitoring and toxicological studies. It is primarily utilized by analytical laboratories, environmental testing facilities, and research institutions specializing in persistent organic pollutant (POP) analysis and regulatory compliance.

Application

• Analytical Reference Standard: Serves as a critical certified reference material (CRM) for the calibration of instruments and validation of analytical methods in gas chromatography (GC) and mass spectrometry (MS).
• Environmental Analysis: Used for the quantification and confirmation of PCB congeners in soil, sediment, water, and biota samples to assess contamination levels and comply with environmental regulations.
• Toxicological Research: Employed in laboratory studies to investigate the specific biological effects, metabolic pathways, and environmental fate of individual PCB congeners.
• Method Development & Validation: Essential for developing, optimizing, and accrediting new analytical procedures for PCB detection and congener-specific analysis.
• Quality Control/Quality Assurance (QC/QA): Used as a spike or internal standard to ensure the accuracy, precision, and reliability of analytical data in commercial and regulatory testing labs.
• Regulatory Compliance Testing: Supports testing mandated by agencies worldwide (e.g., EPA, EU directives) for monitoring PCBs in industrial discharges, waste, and consumer products.
