Description

2,4'-Ddt is a specific isomer of dichlorodiphenyltrichloroethane, a well-known organochlorine compound. This high-purity chemical is critical for research and development, particularly in environmental science and analytical chemistry, where it serves as a certified reference material. It is primarily utilized by analytical laboratories, regulatory agencies, and academic institutions for method validation, quality control, and trace analysis studies.

Application

• Analytical Reference Standard: Serves as a certified standard for the calibration of instruments (GC, GC-MS, HPLC) in environmental and food safety testing.
• Environmental Fate Studies: Used in research to investigate the degradation, metabolism, and persistence of organochlorine compounds in ecosystems.
• Method Development & Validation: Essential for developing and validating analytical methods for pesticide residue analysis in complex matrices.
• Quality Control (QC): Employed as an internal standard or spike in QC protocols for laboratories monitoring pesticide levels.
• Toxicological Research: Used in studies to understand the specific biological activity and toxicity profile of DDT isomers.
• Regulatory Compliance Testing: A key material for testing laboratories ensuring compliance with international regulations on banned or restricted persistent organic pollutants (POPs).
