Description

(±)-2-(2,4-Dichlorophenoxy-D3)Propionic Acid CAS NO 1219803-66-3 is a deuterated isotopologue of the widely used herbicide 2,4-DP (dichlorprop), where three hydrogen atoms are replaced by deuterium. This compound is a critical stable isotope-labeled internal standard for analytical chemistry, enabling precise quantification and method validation in complex matrices. It is essential for researchers and quality control laboratories in the agrochemical, environmental monitoring, and food safety sectors who require the highest accuracy in trace-level analysis.

Application

• Internal Standard for Mass Spectrometry (MS): Primary use as a quantitative internal standard in GC-MS and LC-MS/MS analysis of 2,4-DP and related phenoxy acid herbicides.
• Environmental Analysis: Accurate measurement of herbicide residues in water, soil, and sediment samples for regulatory compliance and environmental fate studies.
• Food Safety Testing: Detection and quantification of pesticide residues in food crops to ensure compliance with Maximum Residue Levels (MRLs).
• Metabolic and Pharmacokinetic Studies: Use in research to track the absorption, distribution, metabolism, and excretion of the parent compound in biological systems.
• Method Development and Validation: Critical for developing robust, high-precision analytical methods in accredited testing laboratories.
• Quality Control in Agrochemical Manufacturing: Ensuring batch-to-batch consistency and purity of commercial herbicide formulations.

Quality Control

Every batch of our stable isotope-labeled materials is produced and tested under strict quality protocols to ensure exceptional isotopic and chemical purity for demanding analytical applications. We provide comprehensive Certificates of Analysis (COA) that detail isotopic enrichment (D, atom %), chemical purity by HPLC, and confirm identity by NMR and MS. Our quality system supports compliance with ISO 17025 and GMP principles for research and regulatory work.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated) for long-term stability. The compound is a strong acid/organic solvent and should be handled in a well-ventilated area. Keep the container tightly sealed to prevent moisture absorption and potential degradation.
