Description

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

Application

• Analytical Reference Standard: Primary use as a high-purity certified reference material (CRM) for the quantification of PCBs in environmental samples via GC-MS or GC-ECD.
• Environmental Monitoring: Calibration and quality control in the analysis of soil, sediment, water, and biota for regulatory compliance with global POPs treaties (e.g., Stockholm Convention).
• Toxicological Research: Used 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 separation in complex matrices.
• Forensic Source Identification: Aiding in the chemical fingerprinting of PCB mixtures to trace contamination sources and understand environmental fate.
• Quality Assurance/Quality Control (QA/QC): Serving as an internal standard or spike recovery standard in laboratory proficiency testing and accreditation processes.
