Description

2,2',6-Trichlorobiphenyl is a specific chlorinated biphenyl congener identified by CAS No. 38444-73-4. This compound is of significant interest in analytical chemistry and environmental science, primarily serving as a critical reference standard for the calibration and validation of analytical methods. It is essential for researchers and quality control laboratories in the environmental monitoring, industrial hygiene, and regulatory compliance sectors who require precise quantification of polychlorinated biphenyl (PCB) congeners in various matrices.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for gas chromatography (GC) and mass spectrometry (MS) calibration in environmental and food testing laboratories.
• Environmental Monitoring: Used in the analysis of soil, sediment, water, and air samples to track PCB contamination and assess remediation efforts.
• Toxicological Research: Serves as a pure congener for studying the specific biological effects, metabolism, and environmental fate of individual PCB compounds.
• Method Development & Validation: Critical for developing, optimizing, and validating new analytical protocols for PCB detection and quantification to meet regulatory standards (e.g., EPA methods).
• Quality Assurance/Quality Control (QA/QC): Employed as an internal or external standard to ensure the accuracy and precision of analytical data in commercial testing labs.
• Regulatory Compliance Testing: Essential for industries requiring monitoring of PCB levels in waste streams, products, or workplace environments to comply with global regulations like the Stockholm Convention.
