Isobutyronitrile is a complex organic molecule that has recently been 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. The backbone is also larger than usual, in comparison with others.
