Description

4-Fluoroaniline--D4 is a deuterium-labeled analog of 4-fluoroaniline, a key building block in advanced chemical synthesis. This isotopically labeled compound is essential for applications requiring precise molecular tracking and analysis, such as in mass spectrometry and NMR studies. It is particularly valuable for researchers and manufacturers in the pharmaceutical, agrochemical, and analytical chemistry sectors who require high-purity, stable isotopic standards for method development and metabolic research.

Application

• Pharmaceutical Research & Development: Used as an internal standard or tracer in drug metabolism and pharmacokinetics (DMPK) studies, enabling accurate quantification of parent compounds and metabolites via LC-MS/MS.
• Agrochemical Analysis: Serves as a labeled standard for the environmental and residue analysis of pesticides and herbicides derived from aniline chemistry.
• Organic Synthesis Intermediate: Acts as a deuterated building block for synthesizing more complex labeled molecules for research purposes.
• Analytical Chemistry: Employed in the development and validation of analytical methods, ensuring precision and reliability in quantitative measurements.
• Material Science Research: Utilized in the study of reaction mechanisms and polymer chemistry where isotopic labeling is required to track specific pathways.
