Description

1,2,4,8,9-Pncdf is a specific polychlorinated dibenzofuran (PCDF) congener, a class of compounds of significant environmental and analytical interest. It is primarily utilized as a high-purity reference standard for analytical and research purposes. This compound is essential for laboratories and industries involved in environmental monitoring, toxicological studies, and regulatory compliance testing for persistent organic pollutants (POPs).

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration and validation of analytical instruments like GC-MS and HRGC/HRMS in environmental and food testing laboratories.
• Environmental Analysis: Critical for the accurate quantification and monitoring of dioxin-like compounds in soil, water, air, and sediment samples to assess contamination levels.
• Toxicological Research: Used in scientific studies to investigate the specific toxicokinetics, metabolic pathways, and health effects of individual PCDF congeners.
• Quality Control & Method Development: Serves as a key component in developing and verifying analytical methods for dioxin and furan analysis according to EPA, EU, and other international standards.
• Regulatory Compliance Testing: Essential for industries (e.g., waste incineration, chemical manufacturing) to test emissions and products to ensure they meet strict regulatory limits for dioxins and furans.
• Food and Feed Safety: Employed in the analysis of foodstuffs, animal feed, and biological tissues to ensure compliance with maximum residue levels (MRLs) set by food safety authorities.

Quality Control

Our high-purity reference materials are produced and handled under strict quality-controlled conditions. Each batch is characterized using state-of-the-art analytical techniques, including gas chromatography and mass spectrometry, to ensure identity, purity, and stability. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with every unit, supporting GLP/GMP compliance and traceability for your critical research and regulatory work.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated) or as indicated on the label or Certificate of Analysis. For long-term storage, keep at -20°C. Allow the vial to equilibrate to room temperature before opening to prevent moisture condensation.
