Benzyl cyanide

Benzyl cyanide (BnCN), also known as phenylacetonitrile or benzeneacetonitrile, is an organic compound with the formula C6H5CH2CN. It is a colorless liquid that is soluble in organic solvents. Benzyl cyanide is used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals.

Production

Benzyl cyanide can be produced by the ammoniation of benzyl chloride in the presence of a base, typically sodium amide or potassium amide, in a liquid ammonia solution. Another method involves the catalytic hydrogenation of phenylacetonitrile.

Uses

Benzyl cyanide is a precursor to several pharmaceuticals and agrochemicals. It is used in the synthesis of phenethylamines, a class of compounds with various applications in drug development. It is also a starting material for the production of alpha-phenylacetoacetonitrile (APAAN), a precursor to the manufacture of amphetamine and methamphetamine.

Safety

Benzyl cyanide is toxic and poses significant health risks if inhaled, ingested, or comes into contact with skin. It can cause respiratory distress, skin irritation, and eye damage. Proper safety measures, including the use of personal protective equipment (PPE), are essential when handling this chemical.

Environmental Impact

The environmental impact of benzyl cyanide is associated with its toxicity and potential for bioaccumulation. It should be handled with care to prevent release into the environment.
