Chemical Structure
Description
The molecular framework of S-Phenyl 4-(benzo[d]oxazol-2-yl)benzothioate (C20H13NO2S) is characterized by a steroid core, an amide group, a sulfone group, 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).
S-Phenyl 4-(benzo[d]oxazol-2-yl)benzothioate (CAS 62572-77-4), molecular formula C20H13NO2S and molecular weight 331.39 g/mol, is a CATO reference standard with documented purity and traceability.
