Description

2,4',5-Trichlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a well-studied class of industrial chemicals. This compound is of significant importance for research, analytical, and regulatory purposes, serving as a critical reference standard. It is primarily needed by analytical laboratories, environmental testing facilities, and chemical manufacturers engaged in method development, quality control, and compliance testing for PCB contamination.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for gas chromatography (GC) and mass spectrometry (MS) calibration and quantification.
• Environmental Analysis: Critical for testing and monitoring soil, water, sediment, and waste samples for PCB contamination to meet regulatory standards (e.g., EPA methods).
• Food and Feed Safety Testing: Used in laboratories to detect and quantify PCB residues in food products, animal feed, and edible oils.
• Method Development and Validation: Essential for developing, optimizing, and validating analytical methods for PCB detection and profiling.
• Quality Control (QC) and Proficiency Testing: Serves as a known component in QC samples and inter-laboratory comparison programs to ensure analytical accuracy.
• Toxicological and Environmental Fate Studies: Used in scientific research to study the behavior, metabolism, and toxicological effects of specific PCB congeners.
