Acetaldehyde-1,2,2,2-d4

Description:

Acetaldehyde-1,2,2,2-d4, also known as deuterated acetaldehyde, is a stable isotopologue of acetaldehyde where four hydrogen atoms are replaced by deuterium, a heavier isotope of hydrogen. Its molecular formula is C2D4O, and it retains the characteristic functional group of aldehydes, which is the carbonyl group (C=O) at one end of the molecule. This compound is colorless and has a pungent odor, similar to that of regular acetaldehyde. Acetaldehyde-1,2,2,2-d4 is primarily used in research and analytical chemistry, particularly in studies involving nuclear magnetic resonance (NMR) spectroscopy, where the presence of deuterium provides enhanced resolution and sensitivity. The presence of deuterium also affects the physical properties, such as boiling and melting points, compared to its non-deuterated counterpart. Additionally, it is utilized in various chemical syntheses and as a solvent in certain applications. As with other aldehydes, it is important to handle acetaldehyde-1,2,2,2-d4 with care due to its potential toxicity and flammability.

Stability Volatile
Applications Labelled Acetaldehyde (A132600) which is used as a marker to determine ALDH2-deficiency in humans. There is genetic-epidemiologic and biochemical evidence linking this deficiency to acetaldehyde exposure and resulting in cancer of the upper digestive tract (1). It has been used as an agent in the measurement of endogenous epinephrine and norepinephrine in human plasma (2). It is also used to label the amine groups on biogenic monoamine neurotransmitters for simultaneous panel determination (3). Drinking water contaminant candidate list 3 (CCL 3) compound as per United States Environmental Protection Agency (EPA), environmental, and food contaminants.
