Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies 6-Amino-2-(4-(dimethylamino)styryl)quinazolin-4(1H)-one (CAS 134842-08-3), a certified reference material (molecular formula C18H18N4O, MW 306.36 g/mol) for analytical method development and quality control.
The molecular framework of 6-Amino-2-(4-(dimethylamino)styryl)quinazolin-4(1H)-one (C18H18N4O) is characterized by a steroid 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.
