Chemical Structure
Description
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 supplies ((4-Bromophenyl)sulfonyl)phenylalanine (CAS 37642-61-8), a certified reference material (molecular formula C15H14BrNO4S, MW 384.24 g/mol) for analytical method development and quality control.
The molecular framework of ((4-Bromophenyl)sulfonyl)phenylalanine (C15H14BrNO4S) is characterized by a flavonoid 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).
As a certified reference material (CRM), ((4-Bromophenyl)sulfonyl)phenylalanine 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.
