Chemical Structure
Description
Structurally, 1-(5-((4-Chlorophenyl)thio)-4-(2,4-dichlorophenyl)thiazol-2-yl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxylic acid (C20H9Cl3F3N3O2S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 550.79 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
