CATO supplies 3-(Naphthalen-1-yl)-2,4-dioxo-1,2,3,4-tetrahydroquinazoline-7-carboxylic acid (CAS 926268-91-9), a certified reference material (molecular formula C19H12N2O4, MW 332.31 g/mol) for analytical method development and quality control.
The molecular framework of 3-(Naphthalen-1-yl)-2,4-dioxo-1,2,3,4-tetrahydroquinazoline-7-carboxylic acid (C19H12N2O4) 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.
