Description

2,2',5,6'-Tetrachlorobiphenyl CAS NO 41464-41-9 is a specific, high-purity polychlorinated biphenyl (PCB) congener essential for analytical and research applications. This compound serves as a critical reference standard for the accurate identification and quantification of PCB contaminants in environmental, food, and biological samples. It is primarily required by analytical laboratories, environmental testing facilities, and research institutions engaged in regulatory compliance, toxicology studies, and method development.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for calibrating GC-MS, GC-ECD, and HPLC systems in PCB analysis.
• Environmental Monitoring: Quantification of PCB congeners in soil, sediment, water, and air samples to assess pollution levels and compliance with environmental regulations (e.g., EPA methods).
• Food and Feed Safety Testing: Used in the analysis of PCBs in food products, animal feed, and edible oils to ensure safety standards are met.
• Toxicological and Biomedical Research: Serves as a precise standard in studies investigating the metabolism, distribution, and health effects of specific PCB congeners.
• Method Development and Validation: Essential for developing, optimizing, and validating new analytical protocols for PCB detection and separation.
• Quality Control/Quality Assurance (QC/QA): Used as an internal standard or spike in laboratory QC procedures to ensure accuracy and precision of analytical data.
• Forensic Analysis: Aiding in the chemical fingerprinting of PCB mixtures to identify sources of contamination.
