Description

Ethyl-1-13C-Benzene 99 Atom % 13C is a stable isotope-labeled analog of ethylbenzene, where the carbon atom at the 1-position is enriched to 99% with the 13C isotope. This high isotopic purity makes it an essential internal standard and tracer compound for advanced analytical and research applications, ensuring precise quantification and metabolic pathway elucidation. It is primarily utilized by analytical laboratories, pharmaceutical researchers, and chemical manufacturers engaged in isotope dilution mass spectrometry (IDMS), nuclear magnetic resonance (NMR) spectroscopy, and metabolic studies.

Application

• Internal Standard for Quantitative Analysis: Used as a high-purity reference standard in Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS) for the accurate quantification of ethylbenzene and related compounds.
• Metabolic Tracer Studies: Enables the tracking of metabolic pathways and degradation products in pharmacological, environmental, and biochemical research.
• NMR Spectroscopy: Serves as a crucial probe in 13C NMR for structural elucidation and kinetic studies due to its specific isotopic labeling.
• Isotope Dilution Mass Spectrometry (IDMS): Provides the gold standard for achieving highly accurate and precise measurements in forensic, clinical, and environmental analysis.
• Pharmaceutical Research & Development: Facilitates drug metabolism and pharmacokinetics (DMPK) studies to understand the fate of drug candidates in biological systems.
• Chemical Synthesis: Acts as a labeled building block for the synthesis of more complex 13C-labeled organic compounds for research purposes.
