Description

1,2,4,6,7,8-Hxcdf is a specific congener of hexachlorodibenzofuran, a class of polychlorinated dibenzofurans (PCDFs). This compound is of significant importance in analytical and environmental chemistry as a certified reference material for accurate identification and quantification. It is primarily needed by analytical laboratories, regulatory agencies, and research institutions focused on environmental monitoring, food safety, and toxicological studies related to persistent organic pollutants (POPs).

Application

• Certified Reference Standard: Used for the calibration of analytical instruments (GC-MS, HRGC/HRMS) and for quality control in the analysis of dioxin and furan samples.
• Environmental Analysis: Critical for testing soil, sediment, water, and air samples to monitor contamination levels and comply with environmental regulations like the Stockholm Convention.
• Food and Feed Safety: Employed in the analysis of foodstuffs, animal feed, and edible oils to ensure compliance with maximum residue limits (MRLs) for dioxins and PCBs.
• Toxicological Research: Serves as a pure standard in studies investigating the toxicity, environmental fate, and health impacts of chlorinated dibenzofurans.
• Method Development and Validation: Essential for developing, validating, and accrediting analytical methods according to ISO, EPA, and other international standards.
• Waste and Emission Testing: Used to analyze industrial emissions, incineration fly ash, and other waste streams for POPs content.
• Proficiency Testing: Acts as a component in inter-laboratory comparison samples to assess and ensure analytical competency across testing facilities.

Quality Control

Our high-purity reference materials are produced and certified under strict quality management systems. Each batch is characterized using state-of-the-art techniques including high-resolution gas chromatography/mass spectrometry (HRGC/HRMS) to ensure identity and purity. A comprehensive Certificate of Analysis (COA) is provided, detailing the certified concentration, measurement uncertainty, and traceability to primary standards. Our quality protocols are designed to meet the rigorous demands of ISO/IEC 17025 accredited laboratories and global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as specified on the label or COA. For long-term stability, store at or below -20°C. Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation. This material is easily oxidized; store under an inert atmosphere after initial opening.
