Chloroacetonitrile is used in the electrochemical synthesis of cyanoacetic acid with carbon dioxide. It is involved in phase-transfer-catalyzed Darzen's condensation reaction with cyclohexanone. It is also used as an eluent additive in thermospray liquid chromatography/mass spectrometry. Further, it is used to prepare polysubstituted pyrido[1,2-a]benzimidazole by reacting with other reactant such as malononitrile, aromatic aldehyde and pyridine.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
