Description

2,3',4,4'-Tetrachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is of significant importance for research, analytical, and regulatory purposes, particularly in environmental monitoring and toxicology studies. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutant (POP) analysis, method development, and calibration standards.

Application

• Analytical Reference Standard: Used as a certified reference material (CRM) for the qualitative and quantitative analysis of PCB congeners in environmental samples via GC-MS or HPLC.
• Environmental Monitoring: Serves as a critical standard for calibrating equipment to detect and quantify PCB contamination in soil, water, sediment, and air.
• Toxicological Research: Employed in laboratory studies to investigate the specific biological effects, metabolic pathways, and toxicity profiles of individual PCB congeners.
• Method Development & Validation: Essential for developing, optimizing, and validating new analytical methods for PCB detection and congener-specific analysis.
• Quality Control/Assurance: Used as an internal standard or spike in laboratory QC/QA protocols to ensure accuracy and precision in PCB testing.
• Regulatory Compliance Testing: Provides a benchmark for testing compliance with international regulations concerning POPs, such as the Stockholm Convention.
