Chemical Structure
Description
1-(2-Hydroxyethyl)pyridin-2(1H)-one (C7H9NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-(2-Hydroxyethyl)pyridin-2(1H)-one (CAS 64330-83-2) is a high-purity analytical reference standard with the molecular formula C7H9NO2 and a molecular weight of 139.15 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.
