Description

2,3',6-Trichlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a well-studied class of industrial chemicals. This high-purity reference standard is critical for analytical research, environmental monitoring, and regulatory compliance testing. It is primarily utilized by analytical laboratories, environmental agencies, and chemical manufacturers engaged in method development, quality control, and toxicological studies.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration and validation of analytical instruments like GC-MS and HPLC in environmental and food testing laboratories.
• Environmental Monitoring: Essential for the accurate quantification and congener-specific analysis of PCB contamination in soil, water, sediment, and air samples.
• Toxicological Research: Used in scientific studies to investigate the specific biological effects, metabolic pathways, and persistence of individual PCB congeners.
• Method Development & Validation: Serves as a critical component in developing and verifying new analytical methods for PCB detection and profiling.
• Quality Assurance/Quality Control (QA/QC): Employed as an internal standard or spike in laboratory QA/QC protocols to ensure accuracy and precision in PCB analysis.
• Regulatory Compliance Testing: Used to support testing mandated by environmental protection regulations (e.g., EPA methods) worldwide.
