Description

3-Methylsulfonyl-2,3',4',5,6-Pentachlorobiphenyl is a high-purity, specialized polychlorinated biphenyl (PCB) derivative, distinguished by its methylsulfonyl functional group. This compound is of significant value as a critical reference standard and analytical intermediate for environmental monitoring and toxicological research. It is primarily required by analytical laboratories, research institutions, and chemical manufacturers engaged in the study of PCB metabolites, environmental fate, and bioaccumulation studies.

Application

• Environmental Analytical Reference Standard: Used for the calibration and validation of analytical methods (GC-MS, LC-MS) for detecting PCB sulfone metabolites in environmental samples like soil, water, and biota.
• Toxicology and Metabolite Research: Serves as a key intermediate or standard in studies investigating the metabolic pathways, persistence, and toxicological effects of chlorinated biphenyls.
• Method Development and Proficiency Testing: Essential for developing new analytical protocols and as a component in laboratory proficiency testing programs to ensure accurate PCB congener analysis.
• Chemical Synthesis Intermediate: Acts as a building block for the synthesis of more complex molecules for specialized research applications in organic and environmental chemistry.
• Regulatory Compliance and Monitoring: Supports laboratories involved in regulatory compliance testing for persistent organic pollutants (POPs) as per international conventions like the Stockholm Convention.
