Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-((3,4-Dichlorophenyl)amino)quinazolin-4(1H)-one (CAS 61741-40-0), a certified reference material (molecular formula C14H9Cl2N3O, MW 306.15 g/mol) for analytical method development and quality control.
The molecular framework of 2-((3,4-Dichlorophenyl)amino)quinazolin-4(1H)-one (C14H9Cl2N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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.
As a certified reference material (CRM), 2-((3,4-Dichlorophenyl)amino)quinazolin-4(1H)-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.
