Description

2,3,4,6,8-Pentachlorodibenzo-p-Dioxin is a specific, high-purity congener of the polychlorinated dibenzo-p-dioxin (PCDD) family, a class of compounds of significant environmental and toxicological interest. This compound is essential for analytical and research laboratories requiring precise chemical standards for calibration, method development, and toxicological studies. It is primarily used by environmental testing facilities, regulatory bodies, and academic researchers focused on dioxin analysis, environmental fate studies, and risk assessment.

Application

• Analytical Reference Standard: Serves as a critical certified reference material (CRM) for the accurate quantification of dioxins in complex matrices via high-resolution gas chromatography/mass spectrometry (HRGC/HRMS).
• Environmental Monitoring & Compliance Testing: Used to calibrate instruments for detecting and measuring PCDD contamination in soil, water, sediment, and air samples to meet regulatory limits (e.g., EPA Method 1613, 8290).
• Food & Feed Safety Analysis: Employed in the analysis of dioxin levels in foodstuffs, animal feed, and edible oils to ensure compliance with strict international safety standards (EU, FDA).
• Toxicological & Biomedical Research: Provides a pure congener for studying the specific structure-activity relationships, metabolic pathways, and health effects of dioxin isomers.
• Method Development & Validation: Essential for developing, optimizing, and validating new analytical methods for dioxin detection and ensuring laboratory proficiency.
• Quality Control/Quality Assurance (QC/QA): Used as a spike or internal standard to assess the accuracy, precision, and recovery of analytical procedures in testing laboratories.
