Chemical Structure
Description
The molecular framework of 4-((5-(Naphthalen-1-yl)-1,3,4-oxadiazol-2-yl)thio)but-2-yn-1-yl benzoate (C23H16N2O3S) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
