Description

(E)-Deschlorophenyl Fluoxastrobin-D4 is a high-purity, deuterium-labeled analog of the active metabolite of the fungicide Fluoxastrobin. This compound is an essential stable isotope-labeled internal standard for precise quantitative analysis in advanced analytical chemistry. It is primarily required by agrochemical research laboratories, environmental testing facilities, and regulatory bodies for method development, residue analysis, and metabolism studies to ensure food safety and environmental compliance.

Application

• Internal Standard for LC-MS/MS Analysis: Critical for the accurate quantification of Fluoxastrobin and its metabolites in complex matrices.
• Agrochemical Research & Development: Used in metabolism, degradation, and environmental fate studies of strobilurin fungicides.
• Residue Testing Laboratories: Enables compliance testing for maximum residue limits (MRLs) in crops, soil, and water samples.
• Environmental Monitoring: Facilitates the trace analysis of fungicide pollutants in environmental samples.
• Pharmaceutical Impurity Profiling: Serves as a reference standard in related pharmaceutical impurity identification workflows.
• Method Development and Validation: Provides the isotopic purity necessary for developing robust, high-sensitivity analytical methods.
