Description

2',3,4,5-Tetrachlorobiphenyl is a specific, high-purity polychlorinated biphenyl (PCB) congener identified by CAS NO 70362-48-0. This compound is of significant importance as a critical reference standard and analytical standard for environmental monitoring and toxicological research. It is primarily needed by analytical laboratories, research institutions, and environmental agencies involved in the detection, quantification, and study of PCB contamination in various matrices.

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for calibrating equipment and validating methods in the analysis of soil, water, and sediment samples for PCB contamination.
• Food Safety Testing: Serves as a critical standard in the quantification of PCB residues in food products, fish, and animal feed to ensure regulatory compliance.
• Toxicological and Biomedical Research: Employed in studies investigating the metabolism, environmental fate, and specific toxic effects of PCB congeners on biological systems.
• Waste and Industrial Effluent Monitoring: Used as a standard for tracing and quantifying PCBs in industrial waste streams and remediation sites.
• Quality Control and Method Development: Essential for developing, optimizing, and verifying analytical protocols (GC-MS, HPLC) in commercial and regulatory testing laboratories.
• Regulatory Compliance and Proficiency Testing: Provides a benchmark for laboratories participating in inter-laboratory comparison studies and audits to demonstrate analytical competency.
