Description

2,3',4',6-Tetrachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is primarily utilized as a critical analytical standard and reference material for environmental monitoring, toxicological research, and regulatory compliance testing. It serves the essential needs of analytical laboratories, research institutions, and environmental agencies engaged in the identification and quantification of PCB contaminants. Its defined structure is vital for calibrating instruments and validating methods in complex matrix analysis.

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the calibration of GC-MS, GC-ECD, and HPLC systems in the analysis of soil, water, sediment, and biota samples.
• Toxicological and Biomedical Research: Serves as a precise congener standard in studies investigating the metabolism, pharmacokinetics, and toxic effects (e.g., endocrine disruption, carcinogenicity) of PCBs.
• Food and Feed Safety Testing: Employed as an analytical standard in laboratories monitoring PCB residues to ensure compliance with maximum residue limits (MRLs) in food products and animal feed.
• Industrial Hygiene and Occupational Safety: Used to develop and validate methods for monitoring workplace air and surface contamination in industries dealing with historical PCB-containing equipment.
• Method Development and Validation: Essential for researchers and chemists developing new analytical protocols for PCB separation, detection, and confirmation.
• Quality Assurance/Quality Control (QA/QC): Acts as a spike or internal standard in laboratory proficiency testing and inter-laboratory comparison programs.
• Regulatory Compliance and Forensics: Supports laboratories in providing defensible data for regulatory submissions related to environmental site assessments, waste characterization, and forensic investigations.
