1,4-Butanediamine putrescine

Diamine A compound with two amine groups, such as 1,4-butanediamine (putrescine). 

Another source of post-mortem GHB production is putrescine (1,4-butanediamine), a biogenic polyamine initially detected in decaying animal tissues, but now known to be present in all cells, both eukaryotic and prokaryotic, where it is important for cell...

Ubiquitous biological chemical formed by decarboxylation in tissue of ornithine or arginine. Used in biochemical and biological research.

Diamines are even worse. Some indication of how bad-smelling they often are can be gained from their names. 1,4-Butanediamine is called putrescine, and 1,5-pentanediamine is called cadaverine. 

One other characteristic of amines is their odor. Low-molecular-weight amines such as trimethylamine have a distinctive fishlike aroma, while diamines such as cadaverine (1,5-pentanediamine) and putrescine (1,4-butanediamine) have the appalling odors you might expect from their common names. Both these diamines arise from the decomposition of proteins. 

Substances with two amine functions are diamines, two examples of which are 1,4-butanediamine and 1,5-pentanediamine. Their contribution to the smell of dead fish and rotting flesh leads to their descriptive common names, putrescine and cadaverine, respectively.
