Description

Compared with other compounds in its class, the molecular weight of 498.69 g/mol gives 2,4-Dichlorophenyl 4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}benzene-1-sulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2,4-Dichlorophenyl 4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}benzene-1-sulfonate (CAS 338400-30-9), a certified reference material (molecular formula C18H9Cl3F3NO4S, MW 498.69 g/mol) for analytical method development and quality control.

The molecular framework of 2,4-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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
