Chemical Structure
Description
4-((5-Bromo-2-methoxybenzylidene)amino)-3-(3-ethoxyphenyl)-1H-1,2,4-triazole-5(4H)-thione (C18H17BrN4O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
