3-Hydroxy-1-methylpyridin-2(1H)-one (CAS 19365-01-6), molecular formula C6H7NO2 and molecular weight 125.13 g/mol, is a CATO reference standard with documented purity and traceability.
3-Hydroxy-1-methylpyridin-2(1H)-one (C6H7NO2) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
