Description

(±)-Quizalofop-Ethyl-D3 (Propionate-3,3,3-D3) is a deuterium-labeled internal standard of the aryloxyphenoxypropionate (AOPP) herbicide quizalofop-ethyl, essential for precise quantitative analysis in modern agricultural and environmental science. This high-purity isotopically labeled compound is critical for ensuring accuracy and reliability in mass spectrometry-based methods, such as LC-MS/MS, by correcting for analyte loss during sample preparation and instrument variability. It is primarily used by analytical laboratories, agrochemical manufacturers, and regulatory bodies for residue testing, metabolic studies, and environmental fate analysis of quizalofop-ethyl. The compound, identified by CAS NO 1398065-84-3, provides an indispensable tool for high-quality research and compliance monitoring.

Application

• Internal Standard for Residue Analysis: Used as a quantitative reference in LC-MS/MS methods for detecting quizalofop-ethyl residues in crops, soil, and water.
• Metabolism and Pharmacokinetic Studies: Enables tracking and quantification of quizalofop-ethyl and its metabolites in biological systems for agrochemical R&D.
• Environmental Monitoring: Facilitates accurate measurement of quizalofop-ethyl levels in environmental samples to assess contamination and degradation.
• Quality Control and Method Validation: Serves as a critical component in validating analytical methods and ensuring the accuracy of testing protocols in QC laboratories.
• Regulatory Compliance Testing: Supports testing for Maximum Residue Limits (MRLs) to ensure food safety and compliance with global regulations (e.g., EPA, EU).
• Stable Isotope Dilution Assay (SIDA): The deuterium label minimizes matrix effects, providing superior accuracy for complex sample analysis.

Quality Control

Every batch of (±)-Quizalofop-Ethyl-D3 is manufactured and analyzed under strict quality management protocols to ensure the highest standards of isotopic purity and chemical integrity. Our products undergo rigorous quality testing, including NMR (¹H and ¹³C) and High-Resolution Mass Spectrometry (HRMS), to confirm deuteration level and chemical identity. A comprehensive Certificate of Analysis (COA) detailing purity, isotopic enrichment, and solvent content is provided with each shipment. We support compliance with ISO 17025 and GMP guidelines for analytical reference materials.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C in a dry, cool place. This product is hygroscopic (moisture-sensitive); ensure the container is sealed under an inert atmosphere after each use to prevent degradation. For long-term storage, consider storage at -20°C under desiccant.
