Description

C-13Tcdf CAS NO 89059-46-1 is a stable isotope-labeled analog of 2,3,7,8-tetrachlorodibenzofuran, a member of the polychlorinated dibenzofuran (PCDF) family. This 13C-labeled compound serves as a critical internal standard for the precise quantification and analysis of toxic dioxin-like compounds in complex matrices. It is an essential tool for analytical chemists and researchers in environmental monitoring, food safety, and toxicology studies, enabling accurate calibration and method validation in high-resolution gas chromatography/mass spectrometry (HRGC/HRMS).

Application

• Internal Standard for Dioxin Analysis: Primary use as a quantitative internal standard in the analysis of polychlorinated dibenzofurans (PCDFs) and dioxins (PCDDs) via HRGC/HRMS.
• Environmental Monitoring: Calibration standard for testing soil, sediment, water, and air samples for persistent organic pollutant (POP) contamination as per EPA and international guidelines.
• Food and Feed Safety: Used in accredited laboratories to ensure compliance with maximum levels of dioxins and PCBs in foodstuffs, animal feed, and edible oils.
• Toxicological Research: Enables precise pharmacokinetic and metabolic fate studies of dioxin-like compounds in biological systems.
• Quality Assurance/Quality Control (QA/QC): Critical component for method development, recovery studies, and ensuring data integrity in analytical laboratories.
• Regulatory Compliance Testing: Supports testing mandated by regulations such as EU Commission Regulation (EC) No 1881/2006, US EPA Method 1613, and JIS K 0311.

Quality Control

Every batch of C-13Tcdf (CAS 89059-46-1) is manufactured and analyzed to meet the exacting standards required for analytical reference materials. Our rigorous quality testing includes verification of isotopic enrichment (typically >99% 13C12), chemical purity, and conformance to specified concentration in solution. Certificates of Analysis (COA) are provided, detailing batch-specific results from techniques such as NMR, HRMS, and HPLC. We support compliance with ISO/IEC 17025 accredited laboratory requirements.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at 2-8°C. The solution should be kept in a cool, dry, and well-ventilated area away from heat and ignition sources. Allow the vial to reach room temperature before use and handle with appropriate laboratory safety practices.
