Chemical Structure
Description
6-bromo-4-methoxyquinazoline (CAS 915924-79-7), molecular formula C9H7BrN2O and molecular weight 239.07 g/mol, is a CATO reference standard with documented purity and traceability.
6-bromo-4-methoxyquinazoline (C9H7BrN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 6-bromo-4-methoxyquinazoline meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
