2-Chlorobenzonitrile is mainly used as a GC calibration standard for compound identification and method validation and it also serves as an intermediate in chemical synthesis and analytical testing.

To serve as a reference standard for accurate calibration identification and validation in gas chromatography analysis.

2-Chlorobenzonitrile is an aromatic organic compound with a benzene ring substituted by a chlorine atom and a nitrile (-CN) group in the ortho position. It is a colorless to pale yellow liquidsolid (depending on purity) with a characteristic odor. As a GC standard it is highly pure and used for accurate calibration and identification in gas chromatography.
