Description

Anisaldehyde-[7-13C] is a stable isotope-labeled analog of p-anisaldehyde, where the carbon atom at the 7-position is enriched with the 13C isotope. This compound is essential for advanced analytical and research applications requiring precise molecular tracking and quantification. It is primarily utilized by scientists and quality control professionals in the pharmaceutical, agrochemical, and analytical chemistry industries for use as an internal standard in mass spectrometry, metabolic studies, and NMR spectroscopy.

Application

• Internal Standard for Mass Spectrometry (MS): Provides accurate quantification in GC-MS and LC-MS analyses of anisaldehyde and related compounds.
• Metabolic Pathway Tracing: Used in pharmacokinetic and drug metabolism studies to track the fate of the labeled carbon atom.
• NMR Spectroscopy: Serves as a valuable probe in nuclear magnetic resonance studies due to the distinct 13C signal.
• Pharmaceutical Impurity Profiling: Aids in the identification and quantification of process-related impurities and degradants.
• Isotope Dilution Analysis: Enables highly precise measurement of anisaldehyde concentrations in complex matrices.
• Chemical Synthesis Research: Employed in the synthesis of other 13C-labeled fine chemicals and intermediates.
