Description

[4-(4-Fluorophenyl)-6-(1-Methylethyl)-2-(Methylsulfinyl)-5-Pyrimidinyl]-Ethyl Ester-D6 is a deuterated isotopologue of a key pyrimidine-based intermediate, offering a stable, non-radioactive isotopic label for advanced research and development. This compound is essential for applications requiring precise metabolic and pharmacokinetic studies, providing enhanced analytical sensitivity and reliability. It is primarily utilized by pharmaceutical R&D teams, contract research organizations (CROs), and analytical laboratories specializing in drug discovery and development.

Application

• Internal Standard for LC-MS/MS: Serves as a critical, stable isotope-labeled internal standard in quantitative bioanalytical methods for accurate mass spectrometry.
• Drug Metabolism and Pharmacokinetics (DMPK): Used in ADME (Absorption, Distribution, Metabolism, Excretion) studies to track the fate of the parent molecule without isotopic interference.
• Pharmaceutical Impurity Profiling: Aids in the identification and quantification of metabolites and process-related impurities during drug development.
• Mechanistic Studies: Enables detailed investigation of metabolic pathways and enzymatic mechanisms in preclinical research.
• Reference Standard: Functions as a high-purity certified reference material (CRM) for method validation and quality control in analytical laboratories.
