CATO supplies Methyl 3-(4-bromobenzenesulfonamido)-3-[4-(propan-2-yl)phenyl]propanoate (CAS 477858-91-6), a certified reference material (molecular formula C19H22BrNO4S, MW 440.35 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 3-(4-bromobenzenesulfonamido)-3-[4-(propan-2-yl)phenyl]propanoate (C19H22BrNO4S) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
