Ethyl cyanide (CH3CH2CN) was detected by
Johnson et al. toward the
OMC-1 region of the
Orion Molecular Cloud complex and toward
Sgr B2 in 1977.
Due to the amount of ethyl cyanide present in hot core sources,
Brauer et al. reported improved measurements
of the compound's ground state properties in 2009, while
Richard et al. reported properties of the three
isotomers where one normal 12C was replaced with 13C in 2012.
Ethyl cyanide or propionitrile is used
industrially as a feedstock for
fragrances, flavorings, and other compounds.
