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 Ethyl 2-(6,8-dichloro-2-methyl-4-oxoquinazolin-3(4H)-yl)acetate (CAS 55469-83-5), a certified reference material (molecular formula C13H11Cl2N2O3, MW 314.14 g/mol) for analytical method development and quality control.
Ethyl 2-(6,8-dichloro-2-methyl-4-oxoquinazolin-3(4H)-yl)acetate (C13H11Cl2N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
