Chemical Structure
Description
5-Bromopyrimidin-2(1H)-one hydrobromide hydrochloride (CAS 477709-63-0) is a high-purity analytical reference standard with the molecular formula C4H3BrN2OHBrHCl and a molecular weight of 292.36 g/mol.
5-Bromopyrimidin-2(1H)-one hydrobromide hydrochloride (C4H3BrN2OHBrHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 5-Bromopyrimidin-2(1H)-one hydrobromide hydrochloride 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.
