CAS 1758-62-9
:Pyrazine-d4,98 atom % D
Description:
Pyrazine-d4, also known as 1,4-dideuteriopyrazine, is a deuterated derivative of pyrazine, a heterocyclic aromatic compound. Its molecular formula is C4D4N2, indicating that it contains four deuterium atoms, which are isotopes of hydrogen. This compound is characterized by its aromatic structure, featuring a six-membered ring containing two nitrogen atoms at opposite positions. The presence of deuterium enhances its stability and alters its physical properties, making it useful in various applications, particularly in NMR spectroscopy, where it serves as a solvent or reference standard due to its distinct spectral characteristics. Pyrazine-d4 is typically colorless and has a similar odor to its non-deuterated counterpart. It is soluble in organic solvents and is often used in research settings, particularly in studies involving isotopic labeling and tracing. The CAS number 1758-62-9 uniquely identifies this compound in chemical databases, facilitating its recognition and procurement for scientific use.
