Description

1-Nitro-2,3,7,8-Tetrachlorodibenzo-p-Dioxin is a specific, high-purity chlorinated nitro-dioxin compound used as a critical reference standard and analytical reagent. This compound is essential for environmental monitoring, toxicological research, and regulatory compliance testing due to its structural significance. It is primarily required by analytical laboratories, research institutions, and environmental agencies involved in the detection and study of persistent organic pollutants (POPs) and dioxin-related compounds.

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the calibration and validation of analytical methods (GC-MS, HRGC/HRMS) in soil, water, and air pollution studies.
• Toxicological Research: Serves as a key analyte in studies investigating the toxicity, environmental fate, and bioaccumulation of nitrated and chlorinated dioxin congeners.
• Food and Feed Safety Testing: Employed in the accurate quantification of dioxin and dioxin-like compound contaminants to ensure compliance with strict international safety regulations (e.g., EU, FDA).
• Method Development and Proficiency Testing: Critical for developing new analytical protocols and for use in inter-laboratory comparison exercises to ensure data accuracy and reliability.
• Regulatory Compliance and Monitoring: Supports enforcement of global treaties like the Stockholm Convention on Persistent Organic Pollutants by providing a traceable standard for monitoring programs.
• Waste and Emission Characterization: Used in the analysis of industrial emissions and waste incineration byproducts to assess environmental impact and regulatory adherence.

Quality Control

Every batch of 1-Nitro-2,3,7,8-Tetrachlorodibenzo-p-Dioxin is manufactured and handled under strict quality management systems. Our products undergo rigorous identity confirmation, purity analysis, and stability testing to ensure they meet the exacting standards required for analytical and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, analytical methods (e.g., HPLC, GC-MS), and traceability is provided with each 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). This material is light-sensitive (store away from light). For long-term storage, consider storing under inert atmosphere at lower temperatures (e.g., -20°C) to ensure maximum stability.
