Putrescine, or tetramethylenediamine, is a foul-smelling organic chemical compound related to cadaverine, both usually produced during tissue decomposition. It is a toxic diamine formed by putrefaction from the decarboxylation of arginine and ornithine, and is largely responsible for the foul odor of putrefying flesh.
