Description

Heptachlorodibenzo-Para-Dioxin CAS NO 37871-00-4 is a specific, highly chlorinated congener of the polychlorinated dibenzo-p-dioxin (PCDD) family, a class of compounds of significant environmental and toxicological concern. Its precise identification and availability are critical for analytical reference, environmental monitoring, and toxicological research. This compound is primarily required by analytical laboratories, regulatory bodies, and research institutions focused on persistent organic pollutant (POP) analysis, risk assessment, and method development.

Application

• Analytical Reference Standard: Serves as a certified reference material (CRM) for the calibration of instruments and validation of analytical methods in gas chromatography-mass spectrometry (GC-MS).
• Environmental Monitoring: Used as a quantitative standard for detecting and measuring PCDD contamination in soil, water, sediment, and air samples to assess environmental quality.
• Food and Feed Safety Analysis: Essential for testing and ensuring compliance with maximum residue limits (MRLs) for dioxins in foodstuffs, animal feed, and edible oils.
• Toxicological and Biomedical Research: Employed in studies investigating the mechanisms of toxicity, bioaccumulation, and health effects of chlorinated dioxins.
• Quality Assurance/Quality Control (QA/QC): Acts as a spike or internal standard in laboratory proficiency testing and inter-laboratory comparison studies.
• Regulatory Compliance Testing: Supports testing mandated by global regulations such as the Stockholm Convention on POPs, EU directives, and US EPA methods.
• Waste and Emission Characterization: Used to analyze dioxin levels in industrial waste, incinerator emissions, and chemical manufacturing byproducts.

Quality Control

Every batch of our Heptachlorodibenzo-Para-Dioxin is produced and handled under strict quality protocols to ensure identity, purity, and stability. We provide comprehensive Certificates of Analysis (COA) that detail the results of rigorous testing, including assay by GC-MS, confirmation of structure, and purity verification. Our quality system supports compliance with the standards required for high-purity reference materials in analytical and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated) or as indicated on the product label or COA. For long-term storage, solutions should be kept in amber vials under inert atmosphere at -20°C or below. The material should be handled in a well-ventilated area by trained personnel using appropriate personal protective equipment.
