Chemical Structure
Description
The molecular framework of Ethyl 1-(4-(4-bromophenyl)thiazol-2-yl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxylate (C16H11BrF3N3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine 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.
