12diaminobutane

1,4-diaminobutane, also known as putrescine, is an organic compound with the formula C4H12N2. It is a diamine, meaning it has two amine functional groups. Putrescine is a colorless solid at room temperature that is soluble in water and ethanol. It is primarily known for its characteristic foul odor, which is associated with the decomposition of animal tissue.

This compound is produced by the decarboxylation of the amino acid ornithine. It is also found naturally in living organisms, including humans, where it plays a role in cell metabolism. Putrescine is a precursor in the biosynthesis of polyamines such as spermidine and spermine, which are essential for cell growth and proliferation.

Beyond its biological roles, 1,4-diaminobutane is used in the chemical industry. It serves as a building block for the synthesis of polymers, particularly polyamides like nylon. It can also be used in the production of pharmaceuticals and other fine chemicals. While its odor can be strong, it can be masked or modified in various applications.
