Description

2,5-Difluorobenzoic-D3 Acid is a deuterium-labeled isotopologue of 2,5-difluorobenzoic acid, serving as a critical internal standard and tracer in advanced analytical chemistry. This high-purity compound is essential for ensuring accuracy and reliability in quantitative mass spectrometry, particularly for pharmacokinetic and metabolic studies. It is primarily utilized by pharmaceutical R&D laboratories, contract research organizations (CROs), and agrochemical developers requiring precise quantification of the non-labeled parent compound in complex biological matrices.

Application

• Internal Standard for LC-MS/MS: Used as a deuterated internal standard in liquid chromatography-tandem mass spectrometry for the accurate quantification of 2,5-difluorobenzoic acid and related metabolites in bioanalytical assays.
• Drug Metabolism and Pharmacokinetics (DMPK): Facilitates stable isotope dilution analysis to study the absorption, distribution, metabolism, and excretion (ADME) of pharmaceutical candidates.
• Environmental Fate Studies: Employed as a tracer to monitor the degradation and environmental persistence of fluorinated benzoic acid derivatives in agrochemical research.
• Synthetic Intermediate: Acts as a labeled building block for the synthesis of more complex deuterated molecules for use in NMR spectroscopy and mechanistic studies.
• Forensic and Doping Control Analysis: Provides a reliable reference standard for confirmatory testing in forensic toxicology and anti-doping laboratories.
