Chemical Structure
Description
CATO supplies N-(3-Bromophenyl)-2-(N-(1-isopropyl-1H-pyrazol-5-yl)phenylsulfonamido)acetamide (CAS 957041-45-1), a certified reference material (molecular formula C20H21BrN4O3S, MW 477.37 g/mol) for analytical method development and quality control.
The molecular framework of N-(3-Bromophenyl)-2-(N-(1-isopropyl-1H-pyrazol-5-yl)phenylsulfonamido)acetamide (C20H21BrN4O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine 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-(3-Bromophenyl)-2-(N-(1-isopropyl-1H-pyrazol-5-yl)phenylsulfonamido)acetamide 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.
