Description

2,3,3',4',5,6-Hexachlorobiphenyl 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 the development of reference standards. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutant (POP) analysis and regulatory compliance.

Application

• Analytical Reference Standard: Used as a certified reference material (CRM) for the calibration of analytical instruments like GC-MS and HPLC in environmental testing.
• Environmental Monitoring: Serves as a critical standard for the quantification and identification of PCB congeners in soil, water, sediment, and air samples to assess contamination levels.
• Toxicological Research: Employed in laboratory studies to investigate the specific biological effects, metabolic pathways, and toxicity profiles of individual PCB congeners.
• Method Development and Validation: Essential for developing, optimizing, and validating analytical methods for PCB detection and analysis in complex matrices.
• Quality Control/Quality Assurance (QC/QA): Used in laboratory proficiency testing and internal quality control programs to ensure accuracy and precision in PCB analysis.
• Regulatory Compliance Testing: Provides a benchmark for testing against international regulations concerning POPs, such as the Stockholm Convention.
