FAQ

Frequently Asked Questions

Yes, benzonitrile is toxic if ingested, inhaled, or absorbed through the skin and requires careful handling in a controlled laboratory environment.

It is described as having an almond-like odour, characteristic of many nitriles and cyanides, but this should never be deliberately inhaled due to its toxicity.

No, it is not a consumer product. It is an industrial and laboratory chemical used to make other substances like pharmaceuticals, dyes, or rubber chemicals.

They are distinct compounds. Benzonitrile (C₆H₅CN) contains a -CN (cyano) group. Nitrobenzene (C₆H₅NO₂) contains a -NO₂ (nitro) group. They have different chemical properties, toxicities, and uses.
