    $\begingroup$ Try to avoid using Wikipedia as a reference, instead please use something like a scientific paper, the CRC handbook of chemistry / physics "rubber book" or some other source which is better than wikipedia $\endgroup$

    $\begingroup$ @NuclearChemist Wikipedia is known to have varying degrees of accuracy, so it is not to be used blindly. But that article has fourteen references, do you have any reason to recomend not using that particular article? $\endgroup$

  • $\begingroup$ @Jose Yeah, but all 14 references don't back up the premise of this answer ("Putrescine is the cause of the rotting fish odor"). I gave that article a cursory look, and it appeared that most of the references (if not all of them) are references to the properties and biosynthesis of putrescine, and not to the fish-odor claim. :-) $\endgroup$

    $\begingroup$ I upvoted this because I know putrescine to have a major role in the odor of rotting (generic) flesh. However, the distinctive odor of rotting fish is mainly attributed to TMA. In my answer, I did mention that other componds were involved in the odor as well, but TMA was the main factor. $\endgroup$
