Chemical Structure
Description
3,4-Dichlorophenyl 4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}benzene-1-sulfonate (CAS 338414-07-6), molecular formula C18H9Cl3F3NO4S and molecular weight 498.69 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3,4-Dichlorophenyl 4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}benzene-1-sulfonate (C18H9Cl3F3NO4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine 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. 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.
As a certified reference material (CRM), 3,4-Dichlorophenyl 4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}benzene-1-sulfonate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
