Description

2,3,4,4',5,6-Hexachlorobiphenyl is a specific, high-purity congener of polychlorinated biphenyls (PCBs) essential for analytical and research purposes. This compound serves as a critical certified reference material (CRM) and analytical standard for accurate environmental monitoring, toxicological studies, and regulatory compliance testing. It is primarily required by environmental testing laboratories, research institutions, and chemical manufacturers involved in method development, quality control, and the analysis of persistent organic pollutants (POPs).

Application

• Certified Reference Material (CRM) for the calibration of analytical instruments (GC, GC-MS, HPLC).
• Analytical Standard for the quantification and identification of PCB congeners in environmental samples (soil, water, sediment).
• Toxicological Research to study the environmental fate, metabolic pathways, and health effects of specific PCB congeners.
• Method Development & Validation in analytical chemistry laboratories for establishing standard operating procedures (SOPs).
• Quality Assurance/Quality Control (QA/QC) in the production of other PCB standards or in environmental monitoring programs.
• Regulatory Compliance Testing to meet international standards for POPs monitoring under the Stockholm Convention.
