Description

Cymoxanil-D3 (Methoxy-D3) is a deuterium-labeled analog of the systemic fungicide cymoxanil, specifically designed for use as an internal standard in advanced analytical chemistry. This high-purity, isotopically labeled compound is critical for ensuring the accuracy and reliability of quantitative mass spectrometry analyses, particularly in residue testing and environmental fate studies. It is an essential tool for agrochemical researchers, analytical laboratories, and regulatory bodies requiring precise quantification of cymoxanil in complex matrices.

Application

• Internal Standard for LC-MS/MS & GC-MS: Primary application as a quantitative internal standard for the analysis of cymoxanil in environmental samples, food commodities, and biological matrices.
• Agrochemical Research & Development: Used in metabolism studies, pharmacokinetic profiling, and degradation pathway analysis of the parent fungicide.
• Regulatory Compliance & Residue Testing: Enables accurate monitoring and enforcement of maximum residue limits (MRLs) in crops and food products for global regulatory submissions.
• Environmental Fate Studies: Facilitates precise tracking and quantification of cymoxanil and its metabolites in soil, water, and air samples.
• Method Development & Validation: Serves as a key component in developing, optimizing, and validating robust analytical methods according to ISO 17025 and SANCO guidelines.
• Quality Control in Manufacturing: Used as a reference standard to ensure the purity and consistency of technical-grade cymoxanil production batches.
