Description

1,3,4,6,7-Pentachlorodibenzofuran is a specific, high-purity chlorinated dibenzofuran congener, a class of compounds of significant interest in environmental and analytical chemistry. This compound serves as a critical certified reference material (CRM) and analytical standard for precise quantification and method validation. It is primarily required by environmental testing laboratories, regulatory agencies, and research institutions engaged in the analysis of dioxins and furans in complex matrices.

Application

• Certified Reference Material (CRM) for the calibration of analytical instrumentation (GC-MS, HRGC/HRMS).
• Analytical Standard for the quantification of polychlorinated dibenzofurans (PCDFs) in environmental, food, and feed samples.
• Method Development and Validation for laboratories establishing or verifying analytical procedures for dioxin-like compounds.
• Quality Control/Quality Assurance (QC/QA) in monitoring programs to ensure data accuracy and compliance with international standards (e.g., EPA, EU).
• Toxicological and Environmental Fate Studies in academic and industrial research.
• Surrogate or Internal Standard in analytical workflows to correct for recovery and matrix effects.
