Description

Acetanilide (Ring-13C6) is a stable isotope-labeled analog of acetanilide, where all six carbon atoms in the aromatic ring are the carbon-13 (13C) isotope. This compound is an essential internal standard and tracer for quantitative analysis using mass spectrometry, providing unmatched accuracy in pharmacokinetic, metabolic, and environmental fate studies. It is primarily utilized by research institutions, pharmaceutical developers, and analytical laboratories requiring high-precision isotopic dilution methods.

Application

• Internal Standard for LC-MS/MS and GC-MS quantification of acetanilide and related metabolites in biological matrices.
• Tracer in Metabolic Pathway Studies to elucidate the biotransformation and excretion profiles of aniline derivatives.
• Critical reagent in Pharmaceutical R&D for drug metabolism and pharmacokinetics (DMPK) research.
• Calibration standard for Environmental Analysis monitoring aniline-based compounds in water and soil.
• Use in Stable Isotope Labeling (SIL) techniques for proteomics and biomarker discovery.
• Reference material for NMR Spectroscopy due to its defined 13C enrichment.
