Description

Aniline-4-13C is a stable isotope-labeled derivative of aniline, where the carbon atom at the 4-position is enriched with the carbon-13 isotope. This product is essential for advanced analytical and research applications where precise molecular tracking and quantification are required. It is primarily used by researchers and quality control laboratories in the pharmaceutical, agrochemical, and material science industries for internal standard synthesis, metabolic pathway studies, and NMR spectroscopy.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a quantitative reference standard in LC-MS and GC-MS analysis for accurate measurement of aniline and its derivatives in complex matrices.
• Metabolic Pathway Tracing: Employed in pharmaceutical and biochemical research to study the metabolism, distribution, and excretion of aniline-containing compounds using 13C-NMR or MS.
• Synthesis of Labeled Compounds: Serves as a key building block for the synthesis of more complex carbon-13 labeled intermediates, dyes, and pharmaceutical agents.
• Environmental Fate Studies: Applied in research to trace the environmental degradation and transformation pathways of aniline-based chemicals.
• Polymer and Material Science Research: Utilized in the development and analysis of novel polymers and advanced materials where isotopic labeling aids in structural elucidation.
• Quality Control & Method Development: Critical for developing and validating highly specific and sensitive analytical methods in regulatory and industrial QC labs.
