Description

3-Methylsulfonyl-4,5,3',4'-Tetrachlorobiphenyl is a specialized polychlorinated biphenyl (PCB) derivative, distinguished by its methylsulfonyl functional group. This compound is of significant value as a key 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 persistence of halogenated organic pollutants.

Application

• Environmental Analytical Reference Standard: Used for the calibration and validation of analytical methods (GC-MS, HPLC) for detecting PCB sulfone metabolites in environmental samples.
• Toxicology and Metabolite Research: Serves as a critical standard in studies investigating the biotransformation, metabolic pathways, and toxicological profiles of polychlorinated biphenyls.
• Method Development and Quality Control: Employed by testing laboratories to develop, optimize, and ensure the accuracy of assays for complex pollutant analysis.
• Chemical Synthesis Intermediate: Acts as a building block or precursor for the synthesis of more complex molecules in specialized organic chemistry and material science research.
• Regulatory Compliance Testing: Used as a standard to help industries comply with environmental regulations concerning persistent organic pollutants (POPs).
