Description

1,2,3,8,9-Pentachlorodibenzofuran is a specific, high-purity congener of the polychlorinated dibenzofuran (PCDF) family, a class of compounds of significant environmental and analytical interest. This compound serves as a critical certified reference material (CRM) and analytical standard essential for accurate identification and quantification in complex matrices. It is primarily required by environmental testing laboratories, regulatory agencies, and research institutions conducting dioxin and furan analysis to ensure compliance with global environmental and food safety regulations.

Application

• Certified Reference Standard for the calibration of analytical instruments (GC-MS, HRGC-HRMS) in dioxin analysis.
• Quality Control/Assurance Material in environmental monitoring programs for soil, water, and air emissions.
• Method Development and Validation for the detection of polychlorinated dibenzofurans (PCDFs) in various sample types.
• Food and Feed Safety Analysis, used as a standard to monitor contaminant levels and ensure compliance with EU and international maximum limits.
• Toxicological and Environmental Fate Studies to understand the behavior and impact of specific dioxin-like compounds.
• Proficiency Testing for laboratories to demonstrate analytical competency and accreditation (e.g., ISO/IEC 17025).
