Benzyl cyanide (abbreviated BnCN) is an organic aromatic compound with the formula C6H5CH2CN.
Benzyl cyanide is a colorless liquid, immiscible with water, but miscible with other organic solvents.
Benzyl cyanide is sold by chemical suppliers. Since it's classified as List I drug precursor in most countries, it's almost impossible to be acquired by the hobby chemist without a permit. In the United States it is classified as a DEA List I chemical.
- C6H5CH2Cl + NaCN → C6H5CH2CN + NaCl
Oxidative decarboxylation of phenylalanine is another possible route.
- Synthesis of various pharmaceuticals
- Preparation of phenylacetic acid
- Preparation of phenethylamine
Benzyl cyanide is irritant, though it's not very volatile. It has medium toxicity.
In closed bottles, away from light and air.
Can be mixed with a more flammable solvent and burned.
