Chemical Structure
Description
4-cyanophenyl 4-{[3-chloro-5-(trifluoromethyl)-2-pyridinyl]oxy}benzenesulfonate (CAS 338414-06-5), molecular formula C19H10ClF3N2O4S and molecular weight 454.81 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-cyanophenyl 4-{[3-chloro-5-(trifluoromethyl)-2-pyridinyl]oxy}benzenesulfonate (C19H10ClF3N2O4S) contains a flavonoid 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 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 454.81 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.
