3160-38-1 AR-1L3196 s-(2-(4-bromophenyl)-1-((2-(4-bromophenyl)-2-oxoethyl)thio)-2-oxoethyl) 4-methylbenzenesulfonothioate (CAS 3160-38-1) is a high-purity analytical reference standard with the molecular formula C11H18O and a molecular weight of 166.26 g/mol.
The molecular framework of 3160-38-1 AR-1L3196 s-(2-(4-bromophenyl)-1-((2-(4-bromophenyl)-2-oxoethyl)thio)-2-oxoethyl) 4-methylbenzenesulfonothioate (C11H18O) is characterized by a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
