Description

2,4,4',6-Tetrachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a well-studied class of industrial chemicals. This compound is primarily utilized as a critical reference standard and analytical tool in environmental and toxicological research. It is essential for laboratories and organizations involved in monitoring, regulatory compliance, and studying the environmental fate and biological impact of persistent organic pollutants.

Application

• Environmental Analysis Reference Standard: Serves as a certified calibration standard for the precise quantification of PCB congeners in soil, water, sediment, and biological samples via GC-MS or GC-ECD.
• Toxicological Research: Used in scientific studies to investigate the specific metabolic pathways, endocrine-disrupting effects, and toxicokinetics of tetrachlorinated biphenyl isomers.
• Method Development & Validation: Employed by analytical laboratories to develop, optimize, and validate chromatographic separation methods for complex PCB mixtures.
• Quality Control & Assurance: Acts as an internal standard or system suitability check in commercial testing laboratories to ensure accuracy and reliability in PCB analysis for regulatory compliance.
• Food & Feed Safety Testing: Used as a reference material in the analysis of PCB contamination levels in the food chain to ensure compliance with international safety standards.
• Industrial Site Remediation Monitoring: Aids in the fingerprinting and source tracking of PCB contamination at legacy industrial sites, guiding remediation efforts.

Quality Control

Every batch of our 2,4,4',6-Tetrachlorobiphenyl is produced and handled under strict quality protocols to ensure the highest standards of identity, purity, and stability required for analytical applications. We provide comprehensive Certificates of Analysis (COA) that detail purity (by GC), congener-specific identity confirmation, and levels of any critical impurities. Our quality system supports compliance with relevant standards for reference materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). For long-term stability, storage at 2-8°C is recommended. Keep the container sealed to prevent contamination and moisture absorption.
