4-((4-Oxo-3,4-dihydroquinazolin-2-yl)amino)benzoic acid (CAS 100448-60-0), molecular formula C15H11N3O3 and molecular weight 281.27 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-((4-Oxo-3,4-dihydroquinazolin-2-yl)amino)benzoic acid (C15H11N3O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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), 4-((4-Oxo-3,4-dihydroquinazolin-2-yl)amino)benzoic acid 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.
