Description

2,3,3',5'-Tetrachlorobiphenyl is a specific, high-purity polychlorinated biphenyl (PCB) congener, identified by CAS NO 41464-49-7. This compound is essential for analytical and research applications where precise chemical standards are required for calibration, method development, and environmental monitoring. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutant (POP) analysis, toxicology studies, and regulatory compliance.

Application

• Analytical Reference Standard: Used as a certified reference material (CRM) for the calibration of GC-MS, HPLC, and other analytical instruments in environmental testing.
• Environmental Monitoring: Serves as a critical standard for quantifying PCB contamination in soil, water, sediment, and air samples to meet regulatory requirements.
• Toxicological Research: Employed in laboratory studies to investigate the metabolic pathways, bioaccumulation, and specific toxic effects of PCB congeners.
• Method Development & Validation: Essential for developing, optimizing, and validating new analytical methods for the detection of PCBs in complex matrices.
• Quality Control/Assurance: Used as an internal or external standard in laboratory QC protocols to ensure the accuracy and precision of PCB analysis.
• Regulatory Compliance Testing: Provides a benchmark for testing products and materials to ensure they comply with international restrictions on PCBs (e.g., Stockholm Convention, TSCA).
