Cadaverine

Cadaverine is an organic compound with the formula (CH2)5(NH2)2. Classified as a diamine, it is a colorless liquid with an unpleasant odor. It is present in small quantities in living organisms but is often associated with the putrefaction of animal tissue. Together with putrescine, it is largely responsible for the foul odor of putrefying flesh, but also contributes to other unpleasant odors.
