Description

2,2',3',4,5-Pentachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a well-studied class of synthetic organic chemicals. This compound is primarily utilized as a critical reference standard and analytical tool for environmental monitoring and toxicological research. It serves professionals in environmental testing laboratories, regulatory agencies, and academic institutions who require high-purity materials for precise calibration and method validation.

Application

• Analytical Reference Standard: Primary use for calibrating instruments (GC, GC-MS, HPLC) in the quantification of PCB congeners in complex matrices.
• Environmental Analysis: Critical for testing soil, sediment, water, and air samples to assess contamination levels and comply with environmental regulations (e.g., EPA methods).
• Toxicology & Research: Used in scientific studies to investigate the biochemical fate, metabolic pathways, and specific toxic effects of individual PCB congeners.
• Food & Feed Safety Testing: Employed as a standard in the analysis of PCB residues in food products, animal feed, and edible oils to ensure safety standards.
• Quality Control & Method Development: Essential for laboratories developing, validating, and maintaining quality control procedures for PCB analysis.
• Regulatory Compliance: Supports testing mandated by global regulations such as the Stockholm Convention on Persistent Organic Pollutants (POPs).
