CATO supplies Methyl 2-(3-(3-fluoro-4-methylbenzoyl)-4-hydroxy-2-(3-methoxyphenyl)-5-oxo-2,5-dihydro-1H-pyrrol-1-yl)-4-methylthiazole-5-carboxylate (CAS 618072-58-5), a certified reference material (molecular formula C25H21FN2O6S, MW 496.51 g/mol) for analytical method development and quality control.
Structurally, Methyl 2-(3-(3-fluoro-4-methylbenzoyl)-4-hydroxy-2-(3-methoxyphenyl)-5-oxo-2,5-dihydro-1H-pyrrol-1-yl)-4-methylthiazole-5-carboxylate (C25H21FN2O6S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 496.51 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
