Chemical Structure

2-((4-(4-Bromophenyl)-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(4-sulfamoylphenyl)acetamide CAS 477329-42-3 chemical structure

Description

2-((4-(4-Bromophenyl)-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(4-sulfamoylphenyl)acetamide (C21H17BrN6O3S2) 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.
