Description

Compared with other compounds in its class, the molecular weight of 168.58 g/mol gives 2-(5-Chloro-2-oxopyridin-1(2H)-yl)acetonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(5-Chloro-2-oxopyridin-1(2H)-yl)acetonitrile (CAS 124432-35-5), molecular formula C7H5ClN2O and molecular weight 168.58 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2-(5-Chloro-2-oxopyridin-1(2H)-yl)acetonitrile is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 168.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
