Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-bromo-8-oxo-5,8-dihydropyrido[3,2-d]pyrimidine-7-carboxylate.
Ethyl 2-bromo-8-oxo-5,8-dihydropyrido[3,2-d]pyrimidine-7-carboxylate (CAS 1098588-16-9) is a high-purity analytical reference standard with the molecular formula C10H8BrN3O3 and a molecular weight of 298.09 g/mol.
Ethyl 2-bromo-8-oxo-5,8-dihydropyrido[3,2-d]pyrimidine-7-carboxylate (C10H8BrN3O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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. 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), Ethyl 2-bromo-8-oxo-5,8-dihydropyrido[3,2-d]pyrimidine-7-carboxylate 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.
