N-(2-(5-(2-Fluorophenyl)-1-isobutyryl-4,5-dihydro-1H-pyrazol-3-yl)phenyl)methanesulfonamide (CAS 923249-89-2), molecular formula C20H22FN3O3S and molecular weight 403.47 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(2-(5-(2-Fluorophenyl)-1-isobutyryl-4,5-dihydro-1H-pyrazol-3-yl)phenyl)methanesulfonamide (C20H22FN3O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures N-(2-(5-(2-Fluorophenyl)-1-isobutyryl-4,5-dihydro-1H-pyrazol-3-yl)phenyl)methanesulfonamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
