Description

4-Methylsulfonyl-2,2',3',4',5-Pentachlorobiphenyl is a specialized polychlorinated biphenyl (PCB) derivative, distinguished by the presence of a methylsulfonyl functional group. This compound is of significant interest in environmental and analytical chemistry as a model compound and reference standard for studying the metabolism, environmental fate, and toxicological profile of sulfonated PCB metabolites. It is primarily required by research institutions, environmental testing laboratories, and chemical manufacturers engaged in advanced analytical method development and regulatory compliance testing.

Application

• Analytical Reference Standard: For use in gas chromatography (GC) and liquid chromatography (LC) methods to identify and quantify PCB metabolites in complex matrices.
• Environmental Fate Studies: As a tracer compound in research investigating the biodegradation, bioaccumulation, and transformation pathways of PCBs in the environment.
• Metabolite Research: Serving as a key intermediate or standard in biochemical and toxicological studies focusing on the sulfonation metabolic pathway of halogenated aromatics.
• Method Development & Validation: Critical for developing and calibrating advanced analytical techniques like GC-MS/MS or LC-HRMS for ultra-trace detection of persistent organic pollutants (POPs).
• Quality Control Material: Used in proficiency testing and internal quality assurance programs within environmental and contract research laboratories.

Quality Control

Every batch of 4-Methylsulfonyl-2,2',3',4',5-Pentachlorobiphenyl is produced and analyzed under strict quality protocols to ensure identity, purity, and consistency. We employ advanced chromatographic and spectroscopic techniques for verification. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and identification data is provided with each shipment to support your research and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
