Ethyne-1,2-d2, also known as deuterated ethyne or deuterated acetylene, is a chemical compound characterized by the presence of two deuterium atoms replacing the hydrogen atoms in the ethyne molecule (C2H2). Its molecular formula is C2D2, and it is a colorless gas at room temperature with a slightly sweet odor. Ethyne-1,2-d2 is used primarily in scientific research, particularly in studies involving nuclear magnetic resonance (NMR) spectroscopy, due to the unique properties of deuterium. The presence of deuterium alters the vibrational frequencies of the molecule, making it useful for distinguishing between different isotopes in analytical chemistry. Ethyne-1,2-d2 is also flammable and can participate in various chemical reactions typical of alkynes, such as addition reactions. Its CAS number, 1070-74-2, is a unique identifier that facilitates the identification and regulation of this substance in chemical databases and safety protocols. As with all chemicals, appropriate safety measures should be taken when handling ethyne-1,2-d2 to mitigate risks associated with its flammability and potential health effects.
