Chemical Structure
Description
The molecular framework of 4-Chloro-N-((4-ethyl-5-((3-(trifluoromethyl)benzyl)thio)-4H-1,2,4-triazol-3-yl)methyl)benzenesulfonamide (C19H18ClF3N4O2S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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.
