Chemical Structure
Description
As a certified reference material (CRM), 2-{[2-(4-bromophenyl)-2-oxoethyl]sulfanyl}-3-(4-methylphenyl)-3,4-dihydroquinazolin-4-one 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 2-{[2-(4-bromophenyl)-2-oxoethyl]sulfanyl}-3-(4-methylphenyl)-3,4-dihydroquinazolin-4-one (CAS 331972-22-6), a certified reference material (molecular formula C23H17BrN2O2S, MW 465.36 g/mol) for analytical method development and quality control.
The molecular framework of 2-{[2-(4-bromophenyl)-2-oxoethyl]sulfanyl}-3-(4-methylphenyl)-3,4-dihydroquinazolin-4-one (C23H17BrN2O2S) is characterized by a steroid 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 its high hydrophobicity (logP), 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
