Chemical Structure
Description
(E)-({5-[(4-chlorophenyl)sulfanyl]-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl}methylidene)amino benzoate (CAS 321553-22-4), molecular formula C19H13ClF3N3O2S and molecular weight 439.84 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (E)-({5-[(4-chlorophenyl)sulfanyl]-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl}methylidene)amino benzoate (C19H13ClF3N3O2S) 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 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 439.84 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
