Chemical Structure
Description
The molecular framework of [(4E)-6-Methyl-3,4-dihydro-2H-1-benzothiopyran-4-ylidene]amino 3-methylbenzoate (C18H17NO2S) 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).
