Description

2,4,6-Trichlorobiphenyl CAS NO 35693-92-6 is a specific chlorinated derivative of biphenyl, belonging to the polychlorinated biphenyl (PCB) family. This compound serves as a critical reference standard and analytical intermediate for environmental monitoring, toxicology research, and regulatory compliance testing. It is primarily required by analytical laboratories, research institutions, and chemical manufacturers engaged in the study, detection, and remediation of persistent organic pollutants (POPs).

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the calibration of GC/MS and HPLC systems in the analysis of PCB contaminants in soil, water, and biological samples.
• Toxicological Research: Serves as a precise chemical entity in studies investigating the metabolism, environmental fate, and toxic effects of specific PCB congeners.
• Method Development and Validation: Essential for developing and validating analytical methods to meet stringent regulatory requirements for POP monitoring (e.g., EPA, EU directives).
• Quality Control/Assurance: Employed as an internal standard or spike in laboratory QC protocols to ensure accuracy and precision in PCB congener-specific analysis.
• Chemical Synthesis Intermediate: Acts as a building block or precursor in specialized organic synthesis for research purposes, including the preparation of other halogenated compounds.
• Regulatory Compliance Testing: Used by commercial testing laboratories to verify compliance with international regulations on PCB levels in consumer products, electrical equipment, and waste streams.

Quality Control

Our 2,4,6-Trichlorobiphenyl is produced and handled under strict quality protocols to ensure high purity and batch-to-batch consistency, which is paramount for analytical and research applications. Each batch is characterized using advanced analytical techniques including GC-FID, GC-MS, and NMR to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing purity, congener-specific identity, and impurity profile is provided with every shipment to support your quality assurance and regulatory documentation 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). Keep the container tightly sealed to prevent moisture absorption and potential contamination. For long-term storage, consider storage under an inert atmosphere.
