CATO supplies 850814-34-5 A10205 ethyl 4-hydroxy-1-isopentyl-2-oxo-1,2-dihydro-1,8-naphthyridine-3-carboxylate ethyl4-hydroxy-1-isopentyl-2-oxo-1,2-dihydro-1,8-naphthyridine-3-carboxylate (CAS 850814-34-5), a certified reference material (molecular formula C16H20N2O4, MW 304.34 g/mol) for analytical method development and quality control.
The molecular framework of 850814-34-5 A10205 ethyl 4-hydroxy-1-isopentyl-2-oxo-1,2-dihydro-1,8-naphthyridine-3-carboxylate ethyl4-hydroxy-1-isopentyl-2-oxo-1,2-dihydro-1,8-naphthyridine-3-carboxylate (C16H20N2O4) is characterized by a flavonoid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 850814-34-5 A10205 ethyl 4-hydroxy-1-isopentyl-2-oxo-1,2-dihydro-1,8-naphthyridine-3-carboxylate ethyl4-hydroxy-1-isopentyl-2-oxo-1,2-dihydro-1,8-naphthyridine-3-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
