CATO supplies 5-(4-Bromophenyl)-1-(2-(dimethylamino)ethyl)-3-hydroxy-4-(4-isopropoxy-3-methylbenzoyl)-1H-pyrrol-2(5H)-one (CAS 371225-07-9), a certified reference material (molecular formula C25H29BrN2O4, MW 501.41 g/mol) for analytical method development and quality control.
Structurally, 5-(4-Bromophenyl)-1-(2-(dimethylamino)ethyl)-3-hydroxy-4-(4-isopropoxy-3-methylbenzoyl)-1H-pyrrol-2(5H)-one (C25H29BrN2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 501.41 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
