Description

2,4,7-Trichlorodibenzofuran is a specific chlorinated dibenzofuran compound of significant interest in analytical and environmental chemistry. This high-purity reference standard is essential for accurate identification, quantification, and toxicological study of persistent organic pollutants (POPs). It serves as a critical tool for researchers, regulatory bodies, and quality control laboratories engaged in environmental monitoring, food safety, and material analysis to assess contamination levels and ensure compliance with international regulations.

Application

• Environmental Analysis Reference Standard: Primary use as an analytical standard for the detection and quantification of polychlorinated dibenzofurans (PCDFs) in soil, water, air, and sediment samples.
• Food and Feed Safety Testing: Calibrant for GC-MS or HRGC/HRMS systems in laboratories monitoring dioxin and furan contamination in the food chain, supporting compliance with EU and global safety directives.
• Toxicological and Ecotoxicological Research: Used in scientific studies to investigate the environmental fate, bioaccumulation, and toxic effects of chlorinated dibenzofurans.
• Waste and Emission Monitoring: Critical for analyzing industrial process emissions, incinerator outputs, and chemical waste to track the formation and release of hazardous substances.
• Quality Control and Method Validation: Serves as a spike/recovery standard or system suitability check in accredited laboratory methods (e.g., EPA 1613, 8290) to ensure analytical accuracy and precision.
• Regulatory Compliance and Certification: Supports testing for REACH, POPs Regulation (EU) 2019/1021, and Stockholm Convention compliance in industrial chemicals and products.

Quality Control

Our 2,4,7-Trichlorodibenzofuran is manufactured and handled under strict quality protocols to ensure the integrity required for trace-level analytical applications. Each batch is characterized using advanced techniques including gas chromatography (GC) and mass spectrometry (MS) to confirm identity and purity. A comprehensive Certificate of Analysis (COA) is provided, detailing batch-specific purity, chromatographic data, and storage recommendations to support your ISO 17025 accredited methods and regulatory submissions.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive nature and organic compound characteristics, the material should be kept away from strong acids and oxidizing agents. For long-term stability, consider storage under inert atmosphere.
