Acetic acid-2-13C,2,2,2-d3 (CAS 79562-15-5)

Acetic acid-2-13C,2,2,2-d3 is a specific isotope-labeled form of acetic acid, a simple carboxylic acid. Carboxylic acids are characterized by a carbonyl group (C=O) and a hydroxyl group (-OH) attached to the same carbon atom. The "acetic acid" part of the name describes the base molecule. Acetic acid is one of the simplest carboxylic acids, consisting of a two-carbon chain with a carboxyl group (COOH) at one end. The "2-13C" part of the name indicates that the carbon atom at the 2nd position (in the case of acetic acid, this is the carbon in the carboxyl group) is an isotope of carbon, specifically carbon-13. Carbon-13 is a stable isotope of carbon that has one extra neutron compared to the most common isotope, carbon-12. The "2,2,2-d3" part of the name indicates that the three hydrogen atoms attached to the carbon-13 atom are all replaced by deuterium atoms. Deuterium, often represented by the symbol D, is a stable isotope of hydrogen that has one extra neutron compared to the most common isotope of hydrogen. In terms of its physical properties, Acetic acid-2-13C,2,2,2-d3 is likely a clear, colorless liquid at room temperature, like regular acetic acid. It is a polar compound due to the presence of the carboxyl group, so it is miscible with water and many other polar solvents. Overall, Acetic acid-2-13C,2,2,2-d3 is useful in the field of chemical research. As a isotope-labeled acetic acid, it can be used for various analytical purposes, including nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry, where the carbon-13 and deuterium atoms can provide unique signals that help in identifying and understanding the structure of the molecule and its reactions. Its chemical structure as a simple carboxylic acid also provides a foundation for understanding and studying the behavior of this important class of organic compounds.
