CATO supplies 6-Bromo-3-hydroxy-2-(o-tolyl)quinazolin-4(3H)-one (CAS 338774-69-9), a certified reference material (molecular formula C15H11BrN2O2, MW 331.16 g/mol) for analytical method development and quality control.
The molecular framework of 6-Bromo-3-hydroxy-2-(o-tolyl)quinazolin-4(3H)-one (C15H11BrN2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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.
