Description

Carbendazim D3 is a deuterium-labeled analog of the widely used systemic benzimidazole fungicide carbendazim, serving as a critical internal standard for precise analytical quantification. This stable isotope-labeled compound is essential for ensuring accuracy and reliability in mass spectrometry-based methods, eliminating matrix effects and enabling definitive identification. It is primarily required by analytical laboratories, agrochemical researchers, and environmental testing facilities engaged in residue analysis, metabolic studies, and method development for compliance and research purposes.

Application

• Internal Standard for LC-MS/MS and GC-MS: Used as a quantitative reference standard in the analysis of carbendazim and its metabolites in complex matrices.
• Agrochemical Residue Testing: Critical for accurate quantification of fungicide residues in food, soil, and water samples to ensure regulatory compliance (e.g., EU MRLs).
• Metabolism and Pharmacokinetic Studies: Enables tracing and quantification of the parent compound and its breakdown products in biological systems for ADME (Absorption, Distribution, Metabolism, Excretion) research.
• Method Development and Validation: Provides a stable, isotopically distinct signal for optimizing and validating analytical methods in accordance with guidelines like SANTE/11312/2021.
• Quality Control in Manufacturing: Supports in-house QC testing for carbendazim-based agrochemical formulations to ensure product consistency and purity.
• Environmental Fate Studies: Aids in research on the degradation, persistence, and movement of carbendazim in the environment.
