Chemical Structure
Description
6-Bromo-3-phenyl-2-sulfanyl-3,4-dihydroquinazolin-4-one (CAS 18009-07-9), molecular formula C14H9BrN2OS and molecular weight 333.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Bromo-3-phenyl-2-sulfanyl-3,4-dihydroquinazolin-4-one (C14H9BrN2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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.
As a certified reference material (CRM), 6-Bromo-3-phenyl-2-sulfanyl-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.
