Description

1,2,4,6,8/1,2,4,7,9-Pentachlorodibenzo-p-Dioxin is a specific, high-purity congener of the polychlorinated dibenzo-p-dioxin (PCDD) family, a class of compounds of significant environmental and toxicological interest. This material is essential for analytical and research laboratories requiring precise chemical standards for calibration, method development, and toxicological studies. It serves as a critical reference standard for environmental monitoring, food safety testing, and regulatory compliance efforts aimed at detecting and quantifying persistent organic pollutants (POPs).

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for the calibration of GC-MS, HRGC/HRMS, and other analytical instrumentation.
• Environmental Analysis: Quantification and monitoring of dioxin contamination in soil, sediment, water, and air samples for environmental impact assessments.
• Food and Feed Safety Testing: Critical component in testing protocols to ensure compliance with strict international regulations (e.g., EU, US FDA) on dioxin levels in foodstuffs, animal feed, and edible oils.
• Toxicological Research: Used in scientific studies to investigate the congener-specific toxicity, environmental fate, bioaccumulation, and health effects of dioxins.
• Method Development & Validation: Serves as a key analyte for developing, optimizing, and validating new analytical methods for PCDD/F detection.
• Quality Control/Quality Assurance (QC/QA): Employed in laboratory proficiency testing and internal quality control programs to ensure accuracy and reliability of analytical data.
• Regulatory Compliance & Certification: Supports testing for regulatory submissions and safety certifications required by agencies worldwide.

Quality Control

Every batch of our 1,2,4,6,8/1,2,4,7,9-Pentachlorodibenzo-p-Dioxin is produced and handled under strict quality management protocols to ensure identity, purity, and stability. The material is characterized using advanced analytical techniques including high-resolution gas chromatography/mass spectrometry (HRGC/HRMS). We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing batch-specific purity, congener confirmation, and solvent content. Our quality system supports compliance with relevant guidelines for reference materials.

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 under an inert atmosphere. Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation.
