Cadaverine is a foul-smelling compound produced by protein hydrolysis during putrefaction of animal tissue. Cadaverine is a toxicdiamine with the formula NH₂(CH₂)₅NH₂, which is similar to putrescine. Cadaverine is also known by the names 1,5-pentanediamine and pentamethylenediamine.

Putrescine and cadaverine were first described in 1885 by the Berlin physician Ludwig Brieger (1849–1919).

Cadaverine is the decarboxylation product of the amino acid lysine.

However, this diamine is not purely associated with putrefaction. It is also produced in small quantities by living beings. It is partially responsible for the distinctive odors of urine and semen.

Elevated levels of cadaverine have been found in the urine of some patients with defects in lysine metabolism.

Cadaverine is toxic in large doses. In rats it had an acute oral toxicity of more than 2000 mg/kg body weight.

Matt Pike (born 1972) is an American rock musician best known as the guitarist of the influential doom metal band Sleep and frontman of High on Fire. He is quite well known in the metal scene for almost never wearing a shirt during live performances.

Pike moved to California after spending time in Military School while living with his mother in Golden, Colorado. A self-proclaimed juvenile delinquent, he was stealing car stereos in order to feed a developing drug habit. When he arrived in Silicon Valley, he realized that the hardcore punk and heavy metal scene was much more active than the one in Denver; he quickly made friends and began going to shows. Pike joined a sludge metal band called Asbestosdeath. After playing around the bay area they developed a much heavier and slower sound. Dubbed doom metal by the press, the quartet soon gained a following and changed their name to Sleep.

When fellow Sleep guitarist Justin Marler decided to quit, Sleep became a power trio. The band's second album, Sleep's Holy Mountain, illustrated Pike as a young Tony Iommi--Playing Black Sabbath-styled riffs that invariably made a profound impact on the developing stoner metal/doom metal scene.
