Description

2,3,4,5,6-Pentachlorobiphenyl is a specific, high-purity congener of polychlorinated biphenyls (PCBs) used primarily as a critical analytical standard and reference material. This compound is essential for environmental monitoring, toxicological research, and regulatory compliance testing due to its defined chemical structure. It is a vital tool for laboratories and industries involved in the analysis of persistent organic pollutants (POPs), calibration of analytical instrumentation, and method development.

Application

• Analytical Reference Standard: Primary use for the calibration and validation of GC, GC-MS, and HPLC systems in environmental and food testing laboratories.
• Environmental Monitoring: Used as a specific congener standard for the quantification of PCB contamination in soil, water, sediment, and air samples to meet regulatory requirements.
• Toxicological Research: Serves as a precise chemical entity in studies investigating the metabolism, bioaccumulation, and toxic effects of individual PCB congeners.
• Method Development & Proficiency Testing: Critical for developing new analytical methods and for use in inter-laboratory comparison programs to ensure data accuracy and reliability.
• Regulatory Compliance & Quality Assurance: Employed to verify laboratory performance and ensure compliance with international standards (e.g., EPA, EU) for POPs analysis.
• Chemical Synthesis Intermediate: Can be used as a building block or precursor in specialized organic synthesis for research purposes.
