Description

2,2',3,3',5-Pentachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a 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: Used as a certified reference material (CRM) for the quantitative and qualitative analysis of PCB congeners in complex matrices via GC-MS or GC-ECD.
• Environmental Monitoring: Essential for calibrating equipment to detect and quantify trace levels of PCBs in soil, water, sediment, and air samples for environmental impact assessments.
• Toxicological Research: Serves as a key material in studies investigating the specific biological effects, metabolic pathways, and persistence of individual PCB congeners.
• Food and Feed Safety Testing: Employed in the analysis of PCB residues to ensure compliance with strict international food safety regulations (e.g., EU, FDA).
• Quality Control and Method Validation: Used by testing laboratories to validate analytical methods, ensure accuracy, and maintain accreditation under standards like ISO/IEC 17025.
• Regulatory Compliance and Forensics: Supports analysis for regulatory enforcement and environmental forensic investigations to identify PCB sources and contamination patterns.
