Description

1,2,3,6,8-Pentachlorodibenzo[1,4]Dioxin is a specific, high-purity chlorinated dioxin congener, identified by CAS NO 71925-16-1. This compound is of significant importance for research, analytical, and regulatory applications where precise chemical standards are required. It is primarily needed by analytical laboratories, environmental testing facilities, and chemical manufacturers involved in the synthesis of reference materials or the study of dioxin toxicology and environmental fate.

Application

• Analytical Reference Standard: Used as a certified reference material (CRM) for the calibration of GC-MS and HPLC systems in environmental and food safety testing.
• Environmental Analysis: Serves as a critical standard for the quantification and monitoring of polychlorinated dibenzo-p-dioxins (PCDDs) in soil, water, and air samples.
• Toxicological Research: Employed in laboratory studies to investigate the specific biological activity, metabolism, and health effects of individual dioxin congeners.
• Method Development & Validation: Essential for developing, optimizing, and validating new analytical methods for dioxin detection and quantification.
• Quality Control: Used as an internal standard or spike in quality control protocols to ensure the accuracy and precision of analytical data in commercial testing labs.
• Regulatory Compliance Testing: Provides a benchmark for compliance testing against international regulations (e.g., EU, US EPA) governing dioxin levels in industrial emissions and consumer products.

Quality Control

Our 1,2,3,6,8-Pentachlorodibenzo[1,4]Dioxin is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatographic purity assessment (GC, HPLC) and confirmatory identification (MS, NMR), to ensure it meets the high standards required for reference materials. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and traceability 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 (typically 15-25°C). For long-term stability, storage under inert atmosphere (e.g., argon or nitrogen) in a freezer (-20°C) is recommended. Keep away from heat and incompatible materials.
