Description

2,4'-Ddt D8 is a deuterium-labeled isotopologue of the organochlorine compound 2,4'-DDT, specifically identified by CAS NO 221899-88-3. This stable isotope-labeled compound is an essential analytical standard, providing critical internal reference points for accurate quantification and method validation in sophisticated mass spectrometry. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions engaged in trace-level analysis, environmental fate studies, and method development for pesticide residues and persistent organic pollutants.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a crucial quantitative reference in GC-MS and LC-MS/MS analysis for the quantification of native DDT isomers and metabolites.
• Environmental Monitoring and Analysis: Used in the testing of soil, water, and biota samples for DDT contamination to assess environmental persistence and bioaccumulation.
• Food Safety and Residue Testing: Employed in laboratories to ensure compliance with maximum residue limits (MRLs) for pesticides in agricultural products and foodstuffs.
• Clinical and Toxicological Research: Facilitates studies on the metabolism, distribution, and long-term effects of DDT and related compounds in biological systems.
• Method Development and Validation: Essential for developing, calibrating, and verifying the accuracy and precision of analytical methods for organochlorine pesticides.
• Quality Control/Assurance in Reference Material Production: Used in the preparation and certification of certified reference materials (CRMs) for analytical laboratories.
