Description

2,3,4,4',6-Pentachlorobiphenyl is a specific congener of the polychlorinated biphenyl (PCB) family, identified by the CAS number 74472-38-1. This compound is of significant interest for environmental analysis, toxicological research, and regulatory compliance testing due to its persistence and bioaccumulative potential. It is primarily required by analytical laboratories, environmental monitoring agencies, and research institutions for use as a high-purity reference standard in chromatography and mass spectrometry.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration and quantification of PCBs in environmental samples via GC-MS or HPLC.
• Environmental Monitoring: Critical for testing soil, water, sediment, and biota to assess contamination levels and compliance with international regulations (e.g., Stockholm Convention).
• Toxicology and Ecotoxicology Studies: Used in research to investigate the specific toxic effects, metabolic pathways, and environmental fate of individual PCB congeners.
• Method Development and Validation: Essential for developing, optimizing, and validating new analytical methods for persistent organic pollutant (POP) detection.
• Quality Control/Quality Assurance (QC/QA): Serves as a spike or recovery standard in laboratory QC procedures to ensure analytical accuracy and precision.
• Regulatory and Forensic Analysis: Supports legal and regulatory testing to identify pollution sources and enforce environmental protection laws.
