Description

4-Methylsulfonyl-2,3,3',4',6-Pentachlorobiphenyl is a highly specific polychlorinated biphenyl (PCB) derivative, distinguished by its methylsulfonyl functional group. This compound is of significant value as a reference standard and analytical standard for environmental monitoring and toxicological research. It is primarily required by analytical laboratories, research institutions, and environmental testing facilities for the precise identification and quantification of PCB metabolites in complex matrices.

Application

• Environmental Analysis Reference Standard: Used for calibrating instruments and validating methods in the detection of PCB sulfone metabolites in soil, water, and sediment samples.
• Toxicological and Metabolic Studies: Serves as a critical standard in research investigating the biotransformation, persistence, and biological effects of polychlorinated biphenyls.
• Method Development and Validation: Essential for developing and confirming the accuracy of advanced analytical techniques such as GC-MS/MS or HRGC/HRMS for persistent organic pollutants (POPs).
• Quality Control/Quality Assurance (QC/QA): Employed as a known compound in laboratory proficiency testing and internal quality control programs to ensure data reliability.
• Regulatory Compliance Testing: Supports testing mandated by environmental protection agencies worldwide for monitoring POPs as listed under the Stockholm Convention.

Quality Control

Every batch of our high-purity reference materials is produced and verified under strict quality management protocols. Identity and purity are confirmed using orthogonal analytical methods including high-resolution mass spectrometry (HRMS), nuclear magnetic resonance (NMR), and high-performance liquid chromatography (HPLC). A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment to ensure traceability and support your regulatory and research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). For long-term stability, storage at -20°C is recommended. Keep the container sealed to prevent moisture absorption and contamination.
