Description

Acetic Acid-13C2 CAS NO 16651-47-1 is a stable isotope-labeled analog of acetic acid, where both carbon atoms are the carbon-13 (13C) isotope. This compound is essential as a critical internal standard and tracer in quantitative analytical techniques, enabling precise measurement and metabolic pathway elucidation. It is primarily required by research institutions, pharmaceutical developers, and analytical laboratories engaged in advanced mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy studies.

Application

• Quantitative Analytical Standard: Serves as an internal standard for the accurate quantification of endogenous acetic acid and related metabolites in complex biological matrices via GC-MS or LC-MS.
• Metabolic Pathway Tracing: Used in 13C-isotope labeling studies to track and map metabolic fluxes in biochemical, microbiological, and pharmaceutical research.
• NMR Spectroscopy: Provides a non-radioactive, stable isotopic label for structural analysis and reaction mechanism studies in chemistry and biochemistry.
• Pharmaceutical Development: Employed in drug metabolism and pharmacokinetics (DMPK) studies to understand the biotransformation of drug candidates.
• Clinical Diagnostics: Potential use in advanced diagnostic assays for detecting metabolic disorders by serving as a labeled reference compound.
• Chemical Synthesis: Acts as a labeled building block for the synthesis of more complex 13C-labeled compounds for research purposes.
