Chemical Structure
Description
As a certified reference material (CRM), 6-Bromo-2-(phenylamino)quinazolin-4(3H)-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.
6-Bromo-2-(phenylamino)quinazolin-4(3H)-one (CAS 284686-84-6), molecular formula C14H10BrN3O and molecular weight 316.15 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Bromo-2-(phenylamino)quinazolin-4(3H)-one (C14H10BrN3O) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
