Putrescine - Wikipedia
WEBPutrescine is an organic compound with the formula (CH 2) 4 (NH 2) 2. It is a colorless solid that melts near room temperature. It is classified as a diamine. [3] Together with cadaverine, it is largely responsible for the foul odor of putrefying flesh, but also contributes to other unpleasant odors.
