Acetic-2-^13C acid, also known as ^13C-labeled acetic acid, is a stable isotope-labeled compound where the carbon atom at the second position of the acetic acid molecule is replaced with the carbon-13 isotope. This modification allows for various applications in research, particularly in nuclear magnetic resonance (NMR) spectroscopy and metabolic studies, as it provides insights into metabolic pathways and molecular dynamics. The compound retains the fundamental characteristics of acetic acid, including its molecular formula (C2H4O2) and its acidic properties, but exhibits distinct NMR signals due to the presence of the ^13C isotope. Acetic-2-^13C acid is typically a colorless liquid with a pungent odor, highly soluble in water, and can participate in various chemical reactions typical of carboxylic acids. Its unique isotopic labeling makes it valuable in tracer studies and in the investigation of biochemical processes, allowing researchers to track the incorporation and transformation of carbon in biological systems.
