Description

1,2,4,6,7,9/1,2,4,6,8,9-Hexachlorodibenzo-p-Dioxin is a chlorinated dioxin congener, a class of compounds of significant environmental and analytical interest. This high-purity chemical standard is critical for research, regulatory compliance, and quality control in environmental monitoring. It is primarily used by analytical laboratories, environmental testing facilities, and research institutions involved in the detection and quantification of persistent organic pollutants (POPs).

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for the calibration of GC-MS and HRGC-HRMS systems in dioxin analysis.
• Environmental Monitoring: Calibration and quality assurance for testing soil, sediment, water, and air samples for polychlorinated dibenzo-p-dioxins (PCDDs).
• Food and Feed Safety Analysis: Used in method development and validation for detecting dioxin contamination in the food chain, supporting compliance with EU and global regulations.
• Toxicological Research: Serves as a specific congener for studying the environmental fate, bioaccumulation, and toxicological profiles of chlorinated dioxins.
• Method Proficiency Testing: Essential component in inter-laboratory comparison studies and accreditation processes for environmental testing labs.
• Waste and Emission Control: Analysis of industrial emissions and waste incineration by-products for regulatory compliance and environmental impact assessments.

Quality Control

Our high-purity analytical standards are produced and verified under strict quality management protocols. Each batch is characterized using state-of-the-art techniques including high-resolution gas chromatography/mass spectrometry (HRGC/HRMS) to ensure congener-specific identity and purity. Certificates of Analysis (COA) detailing exact congener composition, purity, and trace impurity profiles are provided with every shipment to support your ISO 17025 accreditation and data integrity requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. For long-term storage under an inert atmosphere, consult the specific Certificate of Analysis. Handle in accordance with all applicable laboratory safety regulations for toxic compounds.
