Description

2,2',6,6'-Tetrachlorobiphenyl CAS NO 15968-05-5 is a specific, highly chlorinated congener of the polychlorinated biphenyl (PCB) family, valued for its defined chemical structure and utility as a critical analytical standard and research chemical. Its precise configuration makes it an essential reference material for environmental monitoring, toxicological studies, and regulatory compliance testing related to PCB contamination. This compound is primarily required by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutants (POPs).

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration and validation of gas chromatography (GC) and mass spectrometry (MS) instruments in environmental analysis.
• Environmental Monitoring: Critical for the accurate quantification and identification of PCB congeners in soil, water, sediment, and air samples to assess contamination levels.
• Toxicological Research: Used in scientific studies to investigate the specific biological effects, metabolic pathways, and toxicity profiles of individual PCB congeners.
• Method Development & Validation: Serves as a key component in developing and verifying new analytical methods for POP detection and quantification.
• Quality Control & Assurance: Employed in laboratory QC protocols to ensure the accuracy and precision of PCB testing results for regulatory reporting.
• Educational & Training Purposes: Used in academic and professional training settings for chromatography and environmental chemistry instruction.

Quality Control

Every batch of 2,2',6,6'-Tetrachlorobiphenyl is produced and handled under strict quality management protocols to ensure identity, purity, and stability. We provide comprehensive Certificates of Analysis (COA) that detail purity by GC, confirm identity via spectroscopic methods, and report on key impurities. Our quality systems are designed to support GLP (Good Laboratory Practice) and meet the stringent requirements for certified reference materials. Certificates of Analysis (COA) are available upon request.

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). Keep away from strong alkalis and incompatible organic solvents. For long-term stability, consider storage under an inert atmosphere such as argon or nitrogen.
