Description

2,2',4,4',6-Pentachlorodiphenyl Ether is a specific, high-purity polychlorinated diphenyl ether (PCDE) congener. This compound serves as a critical reference standard and analytical intermediate for environmental monitoring and toxicological research. It is primarily required by analytical laboratories, research institutions, and chemical manufacturers engaged in the study of persistent organic pollutants (POPs) and the development of detection methodologies.

Application

• Environmental Analysis Reference Standard: Used as a certified standard for the calibration and quantification of PCDE congeners in environmental samples (water, soil, sediment) via GC-MS or HPLC.
• Toxicological Research: Serves as a pure substance for studying the environmental fate, bioaccumulation, and toxicological profile of chlorinated diphenyl ethers.
• Method Development & Validation: Essential for developing and validating analytical methods in compliance with environmental protection agency guidelines worldwide.
• Chemical Synthesis Intermediate: Acts as a building block or precursor for the synthesis of more complex halogenated organic compounds in specialized research.
• Quality Control Material: Used by producers of analytical kits and laboratories as a quality control check sample to ensure accuracy in POPs analysis.
