Chemical Structure
Description
As a certified reference material (CRM), 3-Bromo-N-cyclopropyl-4-methoxybenzenesulfonamide 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.
CATO supplies 3-Bromo-N-cyclopropyl-4-methoxybenzenesulfonamide (CAS 425656-23-1), a certified reference material (molecular formula C10H12BrNO3S, MW 306.18 g/mol) for analytical method development and quality control.
The molecular framework of 3-Bromo-N-cyclopropyl-4-methoxybenzenesulfonamide (C10H12BrNO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
