Chinese name: Salicylonitrile

　　Foreign name: 2-hydroxy-benzoitril

　　Chinese alias: o-hydroxy Benzonitrile

　　Molecular formula: C7H5NO

　　A gray white powdery solid with a highly irritating odor. A small amount can affect one's breathing, and the odor is bitter and astringent. If a small amount of salicylonitrile is left open without ventilation, the odor can quickly spread throughout the entire room. Therefore, protective measures must be taken during operation to reduce irritation to the respiratory tract.

　　Molecular weight: 119.12

　　Physical and chemical properties: Crystallization. Melting point 92-95 ℃ (102-102.5 ℃), boiling point 149 ℃/1.9kPa (14mmHg), gray white powder solid, highly pungent odor, a small amount can affect people's breathing, and the odor is bitter. If a small amount of salicylonitrile is left open without ventilation, the odor can quickly spread throughout the entire room. Therefore, protective measures must be taken during operation to reduce irritation to the respiratory tract.

　　Usage: Used as an intermediate for the organic synthesis of benilol and as an intermediate for the fungicide azoxystrobin.
