Description

1,7,8-Trichlorodibenzo-p-Dioxin is a specific chlorinated derivative of dibenzo-p-dioxin, a class of compounds of significant interest in environmental and analytical chemistry. This high-purity reference standard is critical for accurate identification, quantification, and toxicological research of dioxin-related compounds. It serves as an essential analytical tool for environmental testing laboratories, regulatory agencies, and research institutions focused on persistent organic pollutant (POP) analysis and chemical safety assessment.

Application

• Environmental Analysis Reference Standard: Primary use as a certified reference material (CRM) for the calibration of GC-MS and HRGC/HRMS systems in the analysis of soil, water, and air samples for dioxin contamination.
• Toxicological Research: Utilized in laboratory studies to investigate the specific biological activity, metabolic pathways, and environmental fate of chlorinated dioxin congeners.
• Method Development and Validation: Essential for developing, optimizing, and validating analytical methods according to international standards like EPA Method 1613 and 8290.
• Quality Control/Quality Assurance (QC/QA): Serves as a spike or internal standard in laboratory QC procedures to ensure the accuracy and precision of dioxin analysis in complex matrices.
• Regulatory Compliance Testing: Used by commercial testing labs to help industries comply with global regulations concerning dioxin emissions and contamination (e.g., Stockholm Convention, REACH).
• Forensic Chemistry: Aids in the chemical fingerprinting and source identification of dioxin contamination in environmental forensic investigations.

Quality Control

Our high-purity analytical standards are produced and verified under strict quality management protocols. Each batch of 1,7,8-Trichlorodibenzo-p-Dioxin is rigorously analyzed using state-of-the-art techniques including GC-MS and HPLC to ensure identity, purity, and stability. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with every shipment, supporting traceability and compliance with ISO/IEC 17025 and ISO Guide 34 principles for reference material producers.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below. Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation. Store in a cool, dry, and well-ventilated area dedicated for hazardous chemicals.
