Chemical Structure
Description
The occurrence of 6-Chloro-3-(2-chlorobenzyl)quinazolin-4(3H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Chloro-3-(2-chlorobenzyl)quinazolin-4(3H)-one (CAS 302913-44-6) is a high-purity analytical reference standard with the molecular formula C15H10Cl2N2O and a molecular weight of 305.16 g/mol.
6-Chloro-3-(2-chlorobenzyl)quinazolin-4(3H)-one (C15H10Cl2N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
