Description

1,2,3,6,7,9-Hexachlorodibenzo-Para-Dioxin is a specific, high-purity chlorinated dioxin congener, a class of compounds of significant interest in analytical and environmental chemistry. This compound serves as a critical certified reference material (CRM) and analytical standard for precise quantification and method validation in complex matrices. It is essential for research laboratories, regulatory bodies, and environmental testing facilities requiring definitive standards for trace-level analysis of persistent organic pollutants (POPs).

Application

• Certified Reference Material (CRM) for the calibration of analytical instruments (GC-MS, HRGC/HRMS).
• Analytical Standard for the quantification of dioxin and furan congeners in environmental, food, and feed samples.
• Method Development and Validation in accordance with EPA Method 1613, 8290, and other international protocols.
• Quality Control/Quality Assurance (QC/QA) programs in commercial and regulatory testing laboratories.
• Toxicological and Environmental Fate Studies to understand congener-specific behavior and impact.
• Internal Standard or Surrogate in analytical procedures to monitor recovery and correct for losses during sample preparation.

Quality Control

Every batch of our 1,2,3,6,7,9-Hexachlorodibenzo-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 congener-specific purity, solvent content, and verification by orthogonal analytical techniques. Our materials are suitable for use under ISO/IEC 17025 accredited laboratory conditions and support compliance with global regulatory frameworks for POPs monitoring.

Storage

Preserve in a tightly closed container, protected from light. Store at -10°C to -20°C in a dedicated freezer. Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation. Store away from strong oxidizers and bases.
