5-Methyl-6-oxo-1,6-dihydropyridine-3-carboxaldehyde (CAS 1289194-02-0) is a high-purity analytical reference standard with the molecular formula C7H7NO2 and a molecular weight of 137.14 g/mol.
5-Methyl-6-oxo-1,6-dihydropyridine-3-carboxaldehyde (C7H7NO2) 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
