CATO supplies (9H-Fluoren-9-yl)methyl (7S,8R,10R)-8,9-bis(hydroxymethyl)-4-oxo-4,6,7,8,9,10-hexahydro-7,10-epiminopyrido[1,2-a]azepine-11-carboxylate (CAS 2204809-84-5), a certified reference material (molecular formula C27H26N2O5, MW 458.51 g/mol) for analytical method development and quality control.
(9H-Fluoren-9-yl)methyl (7S,8R,10R)-8,9-bis(hydroxymethyl)-4-oxo-4,6,7,8,9,10-hexahydro-7,10-epiminopyrido[1,2-a]azepine-11-carboxylate (C27H26N2O5) contains a steroid 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 (9H-Fluoren-9-yl)methyl (7S,8R,10R)-8,9-bis(hydroxymethyl)-4-oxo-4,6,7,8,9,10-hexahydro-7,10-epiminopyrido[1,2-a]azepine-11-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.
