Isobutyronitrile is a complex organic molecule that has been recently found in several meteorites arrived from space. The singularity of this chemical is due to the fact that it is the only one among the molecules arriving from the universe that has a branched, rather than straight, carbon backbone which is larger than usual, in comparison with others.
