CATO supplies tert-butyl (S)-3-methyl-4-((R)-1-methyl-2-oxo-1,2,3,5-tetrahydrobenzo[5,6][1,4]oxazino[3,4-c][1,2,4]triazin-9-yl)-3,6-dihydropyridine-1(2H)-carboxylate (CAS 1613722-45-4), a certified reference material (molecular formula C22H28N4O4, MW 412.48 g/mol) for analytical method development and quality control.
tert-butyl (S)-3-methyl-4-((R)-1-methyl-2-oxo-1,2,3,5-tetrahydrobenzo[5,6][1,4]oxazino[3,4-c][1,2,4]triazin-9-yl)-3,6-dihydropyridine-1(2H)-carboxylate (C22H28N4O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures tert-butyl (S)-3-methyl-4-((R)-1-methyl-2-oxo-1,2,3,5-tetrahydrobenzo[5,6][1,4]oxazino[3,4-c][1,2,4]triazin-9-yl)-3,6-dihydropyridine-1(2H)-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.
