CATO supplies Methyl 3-benzamido-2-oxo-6-[(E)-2-[(4-phenoxyphenyl)amino]ethenyl]-2H-pyran-5-carboxylate (CAS 341966-25-4), a certified reference material (molecular formula C28H22N2O6, MW 482.48 g/mol) for analytical method development and quality control.
Methyl 3-benzamido-2-oxo-6-[(E)-2-[(4-phenoxyphenyl)amino]ethenyl]-2H-pyran-5-carboxylate (C28H22N2O6) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), Methyl 3-benzamido-2-oxo-6-[(E)-2-[(4-phenoxyphenyl)amino]ethenyl]-2H-pyran-5-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
