Description

Methyl 2,4-Dichlorophenoxy-3,5,6-D3-Acetate CAS NO 358731-20-1 is a deuterium-labeled isotopologue of the herbicide methyl 2,4-dichlorophenoxyacetate (Methyl 2,4-D). This compound is a critical analytical standard and internal reference material, enabling precise quantification and metabolic pathway tracing in complex matrices. It is primarily required by research institutions, agrochemical manufacturers, and environmental testing laboratories engaged in advanced analytical chemistry, regulatory compliance testing, and sophisticated agrochemical research and development.

Application

• Internal Standard for Mass Spectrometry (MS): Essential for quantitative analysis (LC-MS/MS, GC-MS) in environmental and biological samples due to its isotopic differentiation from the non-labeled analyte.
• Metabolic and Environmental Fate Studies: Used as a tracer to study the degradation pathways, absorption, and translocation of 2,4-D herbicides in plants, soil, and water systems.
• Method Development and Validation: Serves as a key component in developing and validating robust analytical methods for regulatory submissions and quality control.
• Pharmaceutical Impurity Profiling: Can be utilized in impurity identification and method development where phenoxyacetic acid derivatives are relevant.
• Dioxin and Byproduct Analysis: Applied in research investigating the formation of chlorinated dioxins and other byproducts from phenoxy herbicide degradation.
• Forensic and Residue Analysis: Supports high-accuracy testing for herbicide residues in food, water, and agricultural products to ensure compliance with safety standards.
