Chemical Structure
Description
The molecular framework of 2-oxo-2,3-Dihydro-1H-pyrrolo[2,3-b]pyridine-6-carbonitrile (C8H5N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
2-oxo-2,3-Dihydro-1H-pyrrolo[2,3-b]pyridine-6-carbonitrile (CAS 1190317-09-9) is a high-purity analytical reference standard with the molecular formula C8H5N3O and a molecular weight of 159.14 g/mol.
