Description

2,2',3,3',6-Pentachlorobiphenyl 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 instruments like GC-MS and HPLC in pollutant detection.
• Toxicological Research: Serves as a specific congener for studying the environmental fate, bioaccumulation, and toxic effects of PCBs.
• Regulatory Compliance Testing: Used by testing laboratories to verify analytical methods for compliance with international regulations (e.g., Stockholm Convention, EPA methods).
• Quality Control in Laboratories: Acts as an internal standard or spike for quality assurance/quality control (QA/QC) protocols in environmental sample analysis.
• Method Development and Validation: Critical for developing and validating new analytical techniques for the separation and quantification of PCB congeners in complex matrices.
• Educational and Forensic Analysis: Used in academic settings for teaching advanced analytical chemistry and in forensic investigations to identify pollutant sources.
