Description

1,4,9-Trichlorodibenzofuran is a specific chlorinated dibenzofuran compound, a class of chemicals of significant interest in environmental and analytical chemistry. This high-purity reference material is essential for research, method development, and quality control in laboratories focused on persistent organic pollutants (POPs). It is primarily needed by analytical testing facilities, environmental research institutions, and chemical manufacturers involved in the detection, analysis, and study of dioxin-like compounds.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration and validation of analytical instruments like GC-MS and HRGC/HRMS in dioxin analysis.
• Environmental Monitoring: Critical for the accurate quantification and profiling of polychlorinated dibenzofurans (PCDFs) in soil, water, air, and biota samples.
• Toxicological Research: Used in scientific studies to investigate the environmental fate, behavior, and toxicological profiles of chlorinated aromatic compounds.
• Method Development: Serves as a key component in developing and optimizing new analytical methods for the detection of trace-level halogenated contaminants.
• Quality Assurance/Quality Control (QA/QC): Employed as a spike or internal standard to ensure the accuracy and precision of laboratory testing procedures for POPs.
• Regulatory Compliance Testing: Supports testing to comply with international regulations (e.g., Stockholm Convention, EPA methods) concerning dioxin and furan emissions and contamination.

Quality Control

Our high-purity 1,4,9-Trichlorodibenzofuran is manufactured and handled under strict quality protocols to ensure batch-to-batch consistency and reliability for critical analytical applications. Each lot is rigorously analyzed using advanced techniques including GC-MS and HPLC to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing purity, chromatographic data, and storage recommendations is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). For long-term stability, storage at 2-8°C is recommended. Keep the container tightly sealed in a dry environment to prevent any potential moisture uptake.
