Description

4-Toluidine-D7 is a deuterium-labeled isotopologue of 4-methylaniline, where seven hydrogen atoms are replaced by deuterium. This high-purity stable isotope-labeled compound is essential for use as an internal standard in quantitative mass spectrometry, ensuring analytical accuracy and reliability. It is primarily required by analytical laboratories, pharmaceutical R&D departments, and chemical manufacturers engaged in method development, metabolic studies, and quality control for trace-level analysis of toluidine derivatives.

Application

• Internal Standard for LC-MS/MS and GC-MS quantification of 4-toluidine and related aromatic amines.
• Metabolic Pathway Tracing and pharmacokinetic studies in pharmaceutical research.
• Deuterated Reference Material for NMR spectroscopy and other spectroscopic techniques.
• Environmental Analysis for detecting and quantifying aromatic amine pollutants.
• Dye and Polymer Intermediate research, where isotopic labeling is used to study reaction mechanisms.
• Quality Assurance/Quality Control (QA/QC) in industrial chemical production to monitor process impurities.
