This can be written BuCN, with Bu representing n-butyl. ProductionPentanenitrile can be produced by heating 1-chlorobutane with sodium cyanide in dimethyl sulfoxide. This reaction takes about 20 minutes, keeping the temperature below 160 °C. The yield is about 93%.[1] Another way to get the substance is by heating butyraldehyde with hydroxylamine.[2] Pentanenitrile is contained in bone oil.[3] PropertiesThe pentanenitrile molecule is flexible and can adopt a number of different conformers, so that it will naturally be a mixture. These conformers are called anti-anti (30%), anti-gauche (46%), gauche-anti, gauche-gauche-cis, and gauche-gauche-trans.[4] BiologyPentanenitrile is toxic to animals, and produces its action by the liberation of cyanide by cytochrome P450. The cyanide is detoxifided and excreted in urine as thiocyanate.[5] Pentanenitrile is found in Brassica species and varieties such as broccoli. Pentanenitrile is hydrolyzed to valeric acid by the fungi Gibberella intermedia,[6] Fusarium oxysporum, and Aspergillus niger in which it induces production of the nitrilase enzyme.[7] References1. ^{{cite journal|last1=Smiley|first1=Robert|last2=Arnold|first2=Charles|title=Notes- Aliphatic Nitriles from Alkyl Chlorides|journal=The Journal of Organic Chemistry|date=February 1960|volume=25|issue=2|pages=257–258|doi=10.1021/jo01072a600}} 2. ^{{cite journal|title=Red mud catalyzed one-pot synthesis of nitriles from aldehydes and hydroxylamine hydrochloride under microwave irradiation|journal=Arkivoc|date=5 October 2007|volume=2007|issue=15|pages=162|doi=10.3998/ark.5550190.0008.f16}} 3. ^{{cite book|title=Toxic Substances Control Act (TSCA) Chemical Substance Inventory|date=1979|publisher=the Office|url=https://books.google.com.au/books?id=2psDsfJ3GtoC&pg=RA1-PA2|language=en}} 4. ^{{cite journal|last1=Crowder|first1=G.A.|title=Conformational analysis of n-butyl cyanide|journal=Journal of Molecular Structure: THEOCHEM|date=October 1989|volume=200|pages=235–244|doi=10.1016/0166-1280(89)85056-0}} 5. ^1 {{cite book|last1=Buhler|first1=D.
