Description

2,3,3',4'-Tetrachlorodiphenyl Ether is a specific polychlorinated diphenyl ether (PCDE) congener, a class of compounds structurally related to polychlorinated biphenyls (PCBs). This high-purity chemical standard is critical for analytical and research applications where precise identification and quantification are required. It serves as an essential reference material for environmental scientists, analytical chemists, and regulatory bodies involved in monitoring persistent organic pollutants (POPs) and studying their environmental fate and toxicological profiles.

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the calibration of GC-MS, GC-ECD, and HPLC systems in the analysis of water, soil, sediment, and biota samples.
• Toxicological Research: Employed in laboratory studies to investigate the environmental persistence, bioaccumulation potential, and ecotoxicological effects of chlorinated diphenyl ethers.
• Method Development and Validation: Serves as a key component in developing and validating analytical methods for the detection and separation of complex halogenated aromatic compound mixtures.
• Quality Control/Quality Assurance (QC/QA): Acts as an internal standard or spike recovery standard in analytical laboratories to ensure accuracy and precision in pollutant monitoring programs.
• Regulatory Compliance Testing: Provides a benchmark for laboratories performing compliance testing related to environmental regulations concerning persistent organic pollutants.
• Chemical Synthesis Intermediate: May be utilized as a building block or precursor in specialized organic synthesis for creating novel compounds for research purposes.

Quality Control

Every batch of 2,3,3',4'-Tetrachlorodiphenyl Ether is produced and handled under strict quality management protocols. The material undergoes comprehensive analytical characterization using techniques including GC-FID, GC-MS, and HPLC to confirm identity and establish purity. We provide a detailed Certificate of Analysis (COA) with each shipment, which includes batch-specific data on purity, chromatographic profiles, and physical properties. Our quality systems are designed to meet the stringent requirements of research and analytical laboratories.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). For long-term storage, consider storing under an inert atmosphere to maintain stability. Keep away from heat, sparks, and open flame.
