Aminopropionitrile, also known as β-aminopropionitrile (BAPN), is an organic compound with both amine and nitrile functional groups.

The compound occurs naturally and is of interest in the biomedical community.

[3] Lathyrism, a disease known for centuries, encompasses 2 distinct entities: a disorder of connective tissue, causing either bone deformity (osteolathyrism) or aortic aneurisms (angiolathyrim).

BAPN causes osteolathyrism and angiolathyrism when ingested in large quantities.

[5] Aminopropionitrile is prepared by the reaction of ammonia with acrylonitrile.
