CATO supplies 5-(4-Butoxyphenyl)-4-(3-fluoro-4-methylbenzoyl)-3-hydroxy-1-(pyridin-3-ylmethyl)-1H-pyrrol-2(5H)-one (CAS 618076-09-8), a certified reference material (molecular formula C28H27FN2O4, MW 474.52 g/mol) for analytical method development and quality control.
Structurally, 5-(4-Butoxyphenyl)-4-(3-fluoro-4-methylbenzoyl)-3-hydroxy-1-(pyridin-3-ylmethyl)-1H-pyrrol-2(5H)-one (C28H27FN2O4) contains a steroid core, an amide 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 474.52 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.
