Chemical Structure
Description
CATO supplies 7-Bromo-6-fluoropyrido[3,2-d]pyrimidin-4(3H)-one (CAS 267243-49-2), a certified reference material (molecular formula C7H3BrFN3O, MW 244.02 g/mol) for analytical method development and quality control.
The molecular framework of 7-Bromo-6-fluoropyrido[3,2-d]pyrimidin-4(3H)-one (C7H3BrFN3O) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. 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. 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.
As a certified reference material (CRM), 7-Bromo-6-fluoropyrido[3,2-d]pyrimidin-4(3H)-one 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.
