Description

Octachlorodibenzo-p-Dioxin-13C12 is a stable isotope-labeled (13C12) analog of octachlorodibenzo-p-dioxin (OCDD), a fully chlorinated congener of the dioxin family. This compound is an essential analytical standard for the precise quantification and method validation of OCDD and related persistent organic pollutants (POPs) in complex matrices. It is primarily required by environmental testing laboratories, regulatory agencies, and research institutions engaged in trace-level analysis for food safety, environmental monitoring, and toxicological studies.

Application

• Internal Standard for Mass Spectrometry: Used as a quantitative internal standard in GC-MS and LC-MS/MS analysis to correct for matrix effects and instrument variability.
• Environmental Analysis: Critical for the accurate measurement of OCDD in soil, sediment, water, and air samples to assess contamination and comply with environmental regulations (e.g., EPA Method 1613, 8290).
• Food and Feed Safety Testing: Employed in the analysis of dioxins and furans in foodstuffs, animal feed, and edible oils to ensure compliance with strict EU and international maximum residue limits.
• Human Bio-monitoring: Supports research and testing of dioxin levels in blood, serum, and tissue samples for exposure assessment and epidemiological studies.
• Method Development and Validation: Serves as a certified reference material for developing, calibrating, and validating analytical methods with high accuracy and precision.
• Quality Control/Quality Assurance (QC/QA): Integral to laboratory QC protocols, including recovery studies and proficiency testing schemes.

Quality Control

Every batch of Octachlorodibenzo-p-Dioxin-13C12 is produced and analyzed under strict quality systems to ensure the highest isotopic and chemical purity for trace analytical applications. Our products undergo rigorous quality testing, including NMR and high-resolution mass spectrometry, to confirm isotopic enrichment and chemical identity. Comprehensive Certificates of Analysis (COA) are provided, detailing batch-specific data on purity, isotopic abundance, and solvent content. We support compliance with ISO/IEC 17025 and GMP guidelines for reference materials.

Storage

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