3-(4-Methoxyphenyl)-1-(2-(methylthio)phenyl)propan-1-one (CAS 898775-68-3), molecular formula C17H18O2S and molecular weight 286.39 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(4-Methoxyphenyl)-1-(2-(methylthio)phenyl)propan-1-one (C17H18O2S) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 286.39 g/mol, it falls into the medium-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.
