Chemical Structure

6-Bromo-7-chloroquinazolin-4(3H)-one CAS 17518-95-5 chemical structure

Description

The occurrence of 6-Bromo-7-chloroquinazolin-4(3H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 6-Bromo-7-chloroquinazolin-4(3H)-one (CAS 17518-95-5), a certified reference material (molecular formula C8H4BrClN2O, MW 259.49 g/mol) for analytical method development and quality control.

The molecular framework of 6-Bromo-7-chloroquinazolin-4(3H)-one (C8H4BrClN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. 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. 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.
