Description

1,2,3,4,6,7,8-Hcdf is a specific chlorinated dibenzofuran congener, a compound of significant interest in environmental and analytical chemistry. It serves as a critical reference standard for the accurate identification and quantification of polychlorinated dibenzofurans (PCDFs) in complex matrices. This high-purity material is essential for laboratories and industries requiring precise analytical calibration, environmental monitoring, and toxicological research to ensure regulatory compliance and safety assessments.

Application

• Analytical Reference Standard: Primary use as a certified calibration standard for Gas Chromatography-Mass Spectrometry (GC-MS) and High-Resolution GC-MS (HRGC-MS) analysis of dioxin-like compounds.
• Environmental Testing: Calibration and quality control in the analysis of soil, water, sediment, and air samples for persistent organic pollutant (POP) monitoring programs.
• Food and Feed Safety: Used in methods to detect and quantify PCDF contaminants in food chains, supporting compliance with international safety regulations (e.g., EU, FDA).
• Toxicological Research: Serves as a pure substance for studying the congener-specific toxicity, environmental fate, and metabolic pathways of chlorinated dibenzofurans.
• Industrial Emission Control: Aids in the validation of analytical methods for monitoring emissions from waste incineration and industrial processes to ensure they meet environmental standards.
• Method Development and Validation: Critical for developing, optimizing, and accrediting (ISO/IEC 17025) analytical methods in testing laboratories.
• Regulatory Compliance and Certification: Supports testing for REACH, Stockholm Convention, and other global regulatory frameworks governing POPs.
• Quality Assurance/Quality Control (QA/QC): Used in proficiency testing and inter-laboratory comparison studies to ensure data accuracy and reliability across analytical networks.
