Description

2,2',4,4',5-Pentachlorodiphenyl Ether is a specific, high-purity polychlorinated diphenyl ether (PCDE) congener. This compound is a critical reference standard and research chemical for analytical and environmental studies, particularly in the analysis of persistent organic pollutants. It is primarily required by analytical laboratories, environmental testing facilities, and academic research institutions for use in method development, calibration, and toxicological research.

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the quantification of polychlorinated diphenyl ethers in soil, water, and biota samples.
• Analytical Method Development & Validation: Serves as a critical component in developing and validating GC-MS or HPLC methods for pollutant screening.
• Toxicological and Ecotoxicological Research: Employed in studies investigating the environmental fate, bioaccumulation, and toxic effects of chlorinated aromatic compounds.
• Quality Control & Assurance: Used as an internal standard or spike in laboratory QC procedures to ensure accuracy and precision in analytical results.
• Regulatory Compliance Testing: Essential for laboratories performing testing to comply with environmental regulations concerning persistent organic pollutants (POPs).
• Chemical Intermediate for Specialized Synthesis: May be used in research-scale synthesis of more complex chemical entities for specialized studies.
