Chemical Structure
Description
The molecular framework of 5-Hydroxyquinolin-4(1H)-one (C9H7NO2) is characterized by an amino-acid-derived structure, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
5-Hydroxyquinolin-4(1H)-one (CAS 190516-68-8) is a high-purity analytical reference standard with the molecular formula C9H7NO2 and a molecular weight of 161.16 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.
