CATO supplies 4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}phenyl 4-methoxybenzene-1-sulfonate (CAS 338402-41-8), a certified reference material (molecular formula C20H15ClF3NO4S, MW 457.85 g/mol) for analytical method development and quality control.
The molecular framework of 4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}phenyl 4-methoxybenzene-1-sulfonate (C20H15ClF3NO4S) 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}phenyl 4-methoxybenzene-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.
