Chemical Structure
Description
The molecular framework of 6,7-Dihydro-1H-azepin-2(5H)-one (C6H9NO) is characterized by 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).
6,7-Dihydro-1H-azepin-2(5H)-one (CAS 2228-79-7) is a high-purity analytical reference standard with the molecular formula C6H9NO and a molecular weight of 111.14 g/mol.
