Chemical Structure
Description
The occurrence of 2-((4-(4-Bromophenyl)-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-ethoxyphenyl)acetamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-((4-(4-Bromophenyl)-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-ethoxyphenyl)acetamide (CAS 477330-03-3), molecular formula C23H20BrN5O2S and molecular weight 510.41 g/mol, is a CATO reference standard with documented purity and traceability.
2-((4-(4-Bromophenyl)-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-ethoxyphenyl)acetamide (C23H20BrN5O2S) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
