Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-{3-[(2,4-dichlorophenyl)methoxy]phenyl}-1-(4-fluorobenzenesulfonyl)-1H-pyrazole.
CATO supplies 3-{3-[(2,4-dichlorophenyl)methoxy]phenyl}-1-(4-fluorobenzenesulfonyl)-1H-pyrazole (CAS 956964-63-9), a certified reference material (molecular formula C22H15Cl2FN2O3S, MW 477.34 g/mol) for analytical method development and quality control.
The molecular framework of 3-{3-[(2,4-dichlorophenyl)methoxy]phenyl}-1-(4-fluorobenzenesulfonyl)-1H-pyrazole (C22H15Cl2FN2O3S) is characterized by a steroid 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), 3-{3-[(2,4-dichlorophenyl)methoxy]phenyl}-1-(4-fluorobenzenesulfonyl)-1H-pyrazole 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.
