Chemical Structure
Description
The molecular framework of 1-(1-Ethyl-1H-imidazol-2-yl)butan-1-one (C9H14N2O) 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).
1-(1-Ethyl-1H-imidazol-2-yl)butan-1-one (CAS 540780-96-9) is a high-purity analytical reference standard with the molecular formula C9H14N2O and a molecular weight of 166.22 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
