Chemical Structure
Description
The molecular framework of 1-(3-Chloroquinoxalin-2-yl)butan-1-one (C12H11ClN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
1-(3-Chloroquinoxalin-2-yl)butan-1-one (CAS 2189730-59-2), molecular formula C12H11ClN2O and molecular weight 234.68 g/mol, is a CATO reference standard with documented purity and traceability.
