2,4′-DDT-d₈（Cat No.:R057103）is a deuterium-labeled analog of 2,4′-dichlorodiphenyltrichloroethane (2,4′-DDT), in which eight hydrogen atoms are replaced with deuterium. This isotopically labeled compound is primarily used as an internal standard in analytical chemistry, especially in gas chromatography–mass spectrometry (GC-MS) for the accurate quantification of DDT and its metabolites in environmental and biological samples. 2,4′-DDT-d₈ retains the chemical properties of native DDT, enabling precise tracing without interference. It is essential for monitoring pesticide residues, studying environmental persistence, and assessing bioaccumulation and toxicological effects of organochlorine pollutants in ecological and human health research.
