Description

Fenbendazole Sulfone-D3 is a deuterium-labeled internal standard of the anthelmintic drug metabolite fenbendazole sulfone. This high-purity analytical standard is critical for ensuring accurate quantification and reliable data in complex biological matrices. It is primarily used by pharmaceutical R&D laboratories, contract research organizations (CROs), and analytical testing facilities specializing in veterinary drug residue analysis and pharmacokinetic studies.

Application

• Internal Standard for LC-MS/MS Analysis: Essential for the precise quantification of fenbendazole and its metabolites in tissue, plasma, and feed samples.
• Veterinary Drug Residue Testing: Supports compliance testing for maximum residue limits (MRLs) in food-producing animals to ensure food safety.
• Pharmacokinetic and Metabolism Studies: Enables accurate tracking of drug absorption, distribution, metabolism, and excretion (ADME) in research.
• Method Development and Validation: Serves as a critical reference material for developing and validating robust analytical methods in regulatory environments.
• Quality Control in Reference Material Production: Used in the calibration and verification of other certified reference materials (CRMs).
