Description

Thiabendazole-13C6 is a stable isotope-labeled analog of the broad-spectrum anthelmintic and fungicide, where six carbon atoms are replaced with the carbon-13 isotope. This compound is essential as an internal standard in quantitative mass spectrometry, providing unmatched accuracy and reliability for trace-level analysis. It is critically needed by analytical laboratories and research institutions in the pharmaceutical, agrochemical, and environmental monitoring sectors to ensure precise quantification and method validation.

Application

• Internal Standard for LC-MS/MS: Primary use as a quantitative reference standard in liquid chromatography-tandem mass spectrometry for the analysis of thiabendazole residues.
• Pharmaceutical Metabolism Studies: Enables precise tracking and quantification of drug metabolites in pharmacokinetic and bioavailability research.
• Food Safety Testing: Critical for accurate measurement of thiabendazole pesticide residues in fruits, vegetables, and grains to ensure regulatory compliance.
• Environmental Analysis: Used in monitoring soil and water samples for fungicide contamination and environmental fate studies.
• Method Development & Validation: Serves as a key component in developing and validating robust analytical methods in compliance with FDA, EPA, and EU guidelines.
• Quality Control in Manufacturing: Employed in the QC labs of agrochemical and pharmaceutical manufacturers to ensure product purity and batch consistency.
