CATO supplies 2-((4-Bromophenyl)thio)-4-(4-ethoxyphenyl)-4-oxobutanoic acid (CAS 720667-76-5), a certified reference material (molecular formula C18H17BrO4S, MW 409.29 g/mol) for analytical method development and quality control.
The molecular framework of 2-((4-Bromophenyl)thio)-4-(4-ethoxyphenyl)-4-oxobutanoic acid (C18H17BrO4S) is characterized by a flavonoid core, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
