Description

2,3,4,8-Tcdf is a specific congener of tetrachlorodibenzofuran, a compound of significant interest in environmental and analytical chemistry. Its precise chemical structure makes it a critical reference standard and analytical marker for the detection and quantification of dioxin-like compounds. This high-purity material is essential for research laboratories, regulatory agencies, and environmental testing facilities requiring accurate calibration and method validation.

Application

• Analytical Reference Standard: Primary use as a certified calibration standard for Gas Chromatography-Mass Spectrometry (GC-MS) analysis of polychlorinated dibenzofurans (PCDFs).
• Environmental Monitoring: Quantification of dioxin-like pollutants in soil, water, air, and industrial waste samples to assess contamination levels and regulatory compliance.
• Food and Feed Safety Testing: Used in the analysis of dioxin and furan concentrations to ensure safety standards are met in the food supply chain.
• Toxicological Research: Serves as a precise congener in studies investigating the toxicity, environmental fate, and bioaccumulation of chlorinated dibenzofurans.
• Method Development and Validation: Critical for developing, optimizing, and validating analytical methods in accredited testing laboratories.
• Quality Control/Quality Assurance (QC/QA): Employed as a spike or recovery standard to ensure the accuracy and precision of analytical procedures.

Quality Control

Every batch of our 2,3,4,8-Tcdf is manufactured and handled under strict quality protocols to ensure the highest purity and lot-to-lot consistency required for analytical applications. Identity and purity are confirmed through orthogonal techniques including GC-MS, HPLC, and NMR. A comprehensive Certificate of Analysis (COA) detailing purity, chromatographic data, and storage conditions is provided with each shipment to support your ISO 17025 or GLP compliance.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. Due to its highly volatile nature, allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation and loss of material. For long-term stability, store under an inert atmosphere.
