Description

4-Fluorothioanisole-D4 is a deuterated isotopologue of 4-fluorothioanisole, where four hydrogen atoms are replaced with deuterium. This compound is a valuable stable isotope-labeled standard, essential for ensuring accuracy and reliability in quantitative mass spectrometry analysis. It is primarily used by researchers and quality control laboratories in the pharmaceutical, agrochemical, and analytical chemistry industries for method development, internal standardization, and metabolic studies.

Application

• Internal Standard for Quantitative Analysis: Used as a deuterated internal standard in LC-MS and GC-MS for the precise quantification of its non-deuterated counterpart or related compounds.
• Pharmaceutical Research & Metabolism Studies: Employed in pharmacokinetic, pharmacodynamic, and drug metabolism studies to track and quantify drug molecules and their metabolites.
• Analytical Method Development & Validation: Critical for developing and validating sensitive and specific analytical methods in compliance with regulatory guidelines (e.g., FDA, ICH).
• Environmental and Agrochemical Analysis: Applied in trace analysis of fluorinated aromatic compounds in environmental samples or agrochemical formulations.
• Chemical Synthesis Tracing: Serves as a labeled starting material or intermediate in synthetic chemistry to elucidate reaction mechanisms.
• Quality Control & Reference Standard: Provides a certified reference material for instrument calibration and quality assurance in analytical laboratories.
