Description

4-Methylsulfonyl-3,3',4',5,5'-Pentachlorobiphenyl is a specialized polychlorinated biphenyl (PCB) derivative, distinguished by the presence of a methylsulfonyl functional group. This structural modification makes it a critical compound for advanced research and development, particularly in the study of environmental fate, metabolic pathways, and toxicological profiles of persistent organic pollutants. It serves as a high-purity reference standard and a key synthetic intermediate for scientists and quality control laboratories. This product is essential for organizations in the environmental analysis, analytical chemistry, and life science research sectors requiring precise and reliable chemical standards.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for the calibration of analytical instruments like GC-MS and HPLC in environmental testing laboratories.
• Environmental Fate Studies: Investigation of the transformation, degradation, and bioaccumulation pathways of sulfonated PCB metabolites in ecosystems.
• Toxicological Research: Used in biochemical and cellular assays to study the specific mechanisms of toxicity and endocrine-disrupting effects of PCB derivatives.
• Metabolite Identification: Serves as a definitive standard for identifying and quantifying methylsulfonyl-PCB metabolites in biological and environmental samples.
• Method Development & Validation: Critical for developing, optimizing, and validating new analytical methods for trace-level detection of complex organohalogen compounds.
• Chemical Synthesis: Acts as a sophisticated building block or precursor for the synthesis of more complex molecules for specialized research applications.
