CATO supplies Methyl 3-[2-({2-[3-(trifluoromethyl)benzenesulfonamido]phenyl}sulfanyl)acetamido]thiophene-2-carboxylate (CAS 477887-56-2), a certified reference material (molecular formula C21H17F3N2O5S3, MW 530.56 g/mol) for analytical method development and quality control.
Structurally, Methyl 3-[2-({2-[3-(trifluoromethyl)benzenesulfonamido]phenyl}sulfanyl)acetamido]thiophene-2-carboxylate (C21H17F3N2O5S3) 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 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 530.56 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.
