Acetic acid-d4

Description:
Acetic acid-d4, also known as deuterated acetic acid, is a stable isotopic variant of acetic acid where the hydrogen atoms are replaced by deuterium, a heavier isotope of hydrogen. Its chemical formula is C2D4O2, and it retains the same functional properties as regular acetic acid, including being a colorless liquid with a pungent odor. Acetic acid-d4 is primarily used in nuclear magnetic resonance (NMR) spectroscopy as a solvent and reference standard due to its unique isotopic labeling, which helps in distinguishing signals in NMR studies. The presence of deuterium enhances the resolution of spectral data, making it valuable in research and analytical chemistry. Acetic acid-d4 is miscible with water and exhibits similar acidity to its non-deuterated counterpart, although its physical properties, such as boiling point and density, may differ slightly due to the isotopic substitution. Safety precautions should be observed when handling this substance, as it can be irritating to the skin and eyes.
