The molecular framework of .alpha.-Pyracin 4543-56-0 7-Hydroxy-6-methylfuro[3,4-c]pyridin-3(1H)-one 7-hydroxy-6-methyl-1H-furo[3,4-c]pyridin-3-one NSC15983 Pyracin-5 Pyridoxic acid .gamma.-lactone Pyridoxic acid, .gamma.-lactone {Furo[3,4-c]pyridin-3(1H)-one,} 7-hydroxy-6-methyl- (C8H7NO3) 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. 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.
