CATO supplies (2Z)-2-[(3,4-Dimethoxyphenyl)methylidene]-3-phenyl-7-[3-(trifluoromethyl)phenoxy]-2,3-dihydro-1H-inden-1-one (CAS 337921-81-0), a certified reference material (molecular formula C31H23F3O4, MW 516.51 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system, (2Z)-2-[(3,4-Dimethoxyphenyl)methylidene]-3-phenyl-7-[3-(trifluoromethyl)phenoxy]-2,3-dihydro-1H-inden-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 516.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
