Description

2,2',3-Trichlorobiphenyl CAS NO 38444-78-9 is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is primarily utilized as a critical reference standard and analytical standard in environmental testing and research. It is essential for laboratories and industries involved in the monitoring, analysis, and remediation of persistent organic pollutants (POPs).

Application

• Environmental Analysis Reference Standard: Primary use as a certified reference material (CRM) for calibrating analytical equipment like GC-MS and HPLC in pollutant detection.
• PCB Congener-Specific Research: Used in scientific studies to understand the environmental fate, transport, and toxicological profile of individual PCB congeners.
• Quality Control and Method Validation: Serves as a spike or control sample in laboratory QC procedures to validate testing methods for PCBs in soil, water, and biological tissues.
• Regulatory Compliance Testing: Essential for industries (e.g., waste management, manufacturing) to test effluent and products for compliance with global PCB regulations (e.g., Stockholm Convention, EPA methods).
• Forensic and Diagnostic Applications: Aids in source identification and fingerprinting of PCB contamination in environmental forensic investigations.
• Material and Product Safety Testing: Used to test for the presence of PCBs in older electrical equipment, building materials, and other industrial products.
