Description

Fenbendazole-D3 is a deuterium-labeled analog of the broad-spectrum anthelmintic agent, Fenbendazole. This stable isotope-labeled compound is essential for use as an internal standard in quantitative mass spectrometry, ensuring the highest accuracy and reliability in analytical results. It is a critical tool for researchers and quality control laboratories in the pharmaceutical, veterinary medicine, and agrochemical sectors who require precise quantification of Fenbendazole in complex matrices.

Application

• Primary use as an internal standard in Liquid Chromatography-Mass Spectrometry (LC-MS) and Gas Chromatography-Mass Spectrometry (GC-MS) for the quantification of Fenbendazole.
• Metabolic and pharmacokinetic studies (ADME research) to track the absorption, distribution, metabolism, and excretion of the parent compound.
• Development and validation of high-precision analytical methods in pharmaceutical quality control laboratories.
• Residue testing and monitoring in veterinary and food safety programs to ensure regulatory compliance.
• Use in environmental fate studies to trace the degradation and movement of Fenbendazole in ecosystems.
• Supporting clinical research and bioanalytical assays for therapeutic drug monitoring.
