Description

Pyrimethanil-D5 (Phenyl-D5) is a deuterium-labeled internal standard of the anilinopyrimidine fungicide Pyrimethanil, essential for precise quantitative analysis. This stable isotope-labeled compound is critical for ensuring accuracy and reliability in mass spectrometry-based methods, eliminating matrix effects and instrument variability. It is primarily required by analytical laboratories, agrochemical manufacturers, and regulatory bodies for residue testing, environmental monitoring, and pharmacokinetic studies.

Application

• Internal Standard for LC-MS/MS and GC-MS quantification of Pyrimethanil residues in food, soil, and water samples.
• Metabolite tracing and pharmacokinetic studies in agricultural and environmental research.
• Method development and validation for regulatory compliance in agrochemical analysis.
• Quality control and assurance in the production of fungicide formulations.
• Use in stable isotope dilution assays (SIDA) for high-precision analytical measurements.
• Environmental fate and transport studies of fungicide compounds.
