Description

Clopyralid-13C2,15N is a stable isotope-labeled analog of the widely used pyridinecarboxylic acid herbicide, Clopyralid. This compound is an essential internal standard and reference material for advanced analytical techniques, ensuring precise quantification and reliable data in complex matrices. It is primarily utilized by research institutions, agrochemical manufacturers, and environmental testing laboratories engaged in method development, residue analysis, and metabolic fate studies.

Application

• Quantitative Mass Spectrometry (LC-MS/MS, GC-MS): Serves as a critical internal standard for the accurate quantification of Clopyralid residues in environmental samples (soil, water) and agricultural products, correcting for matrix effects and instrument variability.
• Metabolism and Pharmacokinetic Studies: Used as a tracer to investigate the absorption, distribution, metabolism, and excretion (ADME) pathways of Clopyralid in plants, animals, and environmental systems.
• Method Development and Validation: An indispensable tool for developing, optimizing, and validating highly sensitive and selective analytical methods in compliance with regulatory guidelines (e.g., EPA, EU).
• Quality Control and Assurance: Employed in the quality control laboratories of agrochemical manufacturers to verify the purity and consistency of Clopyralid technical material and formulations.
• Environmental Fate and Leaching Studies: Facilitates precise tracking and modeling of Clopyralid's persistence, mobility, and degradation in the environment.
