Chemical Structure
Description
As a certified reference material (CRM), 3-(4-(((2,4-Diamino-5-methylquinazolin-6-yl)methyl)amino)benzamido)pentanedioic 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.
3-(4-(((2,4-Diamino-5-methylquinazolin-6-yl)methyl)amino)benzamido)pentanedioic acid (CAS 69827-75-4), molecular formula C22H24N6O5 and molecular weight 452.46 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(4-(((2,4-Diamino-5-methylquinazolin-6-yl)methyl)amino)benzamido)pentanedioic acid (C22H24N6O5) is characterized by a flavonoid core, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
