Description

2,3,3',5',6-Pentachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is of significant interest for analytical and research purposes, particularly in environmental monitoring, toxicology studies, and the development of reference standards. It is primarily required by analytical laboratories, research institutions, and chemical manufacturers involved in environmental analysis, regulatory compliance testing, and the synthesis of specialized chemical products.

Application

• Analytical Reference Standard: Used as a certified reference material (CRM) for the calibration of instruments and the quantification of PCBs in environmental samples via GC-MS or HPLC.
• Environmental Monitoring & Research: Critical for studying the fate, transport, and bioaccumulation of specific PCB congeners in soil, water, and biological tissues.
• Toxicological Studies: Employed in laboratory research to investigate the specific health effects, metabolic pathways, and toxicity profiles of pentachlorobiphenyl isomers.
• Method Development & Validation: Serves as a key component in developing and validating new analytical methods for PCB detection and analysis to meet regulatory requirements.
• Quality Control/Assurance: Used by chemical manufacturers and testing laboratories to ensure the accuracy and precision of their analytical results for PCB-containing materials.
• Regulatory Compliance Testing: Essential for testing products and environmental samples to ensure compliance with global regulations restricting PCBs, such as the Stockholm Convention.
