6-Bromo-3-hydroxy-2-phenyl-3,4-dihydroquinazolin-4-one CAS 477864-80-5

Description

6-Bromo-3-hydroxy-2-phenyl-3,4-dihydroquinazolin-4-one (CAS 477864-80-5), molecular formula C14H9BrN2O2 and molecular weight 317.14 g/mol, is a CATO reference standard with documented purity and traceability.

6-Bromo-3-hydroxy-2-phenyl-3,4-dihydroquinazolin-4-one (C14H9BrN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 6-Bromo-3-hydroxy-2-phenyl-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.
