1-(4-Methoxyphenyl)-3-({4-[(4-{[3-(4-methoxyphenyl)-3-oxopropyl]sulfanyl}phenyl)sulfanyl]phenyl}sulfanyl)propan-1-one (CAS 882749-71-5) is a high-purity analytical reference standard with the molecular formula C32H30O4S3 and a molecular weight of 574.77 g/mol.
Structurally, 1-(4-Methoxyphenyl)-3-({4-[(4-{[3-(4-methoxyphenyl)-3-oxopropyl]sulfanyl}phenyl)sulfanyl]phenyl}sulfanyl)propan-1-one (C32H30O4S3) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 574.77 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.
