2-Bromo-1H-purin-6(7H)-one 2-bromo-1,7-dihydro-6h-purin-6-one 2-bromo-3,7-dihydropurin-6-one 2-bromohypoxanthine 2-bromohypoxanthine 96% 6h-purin-6-one, 2-bromo-1,9-dihydro- 87781-93-9 (CAS 87781-93-9) is a high-purity analytical reference standard with the molecular formula C5H7BrN4O and a molecular weight of 219.04 g/mol.
The molecular framework of 2-Bromo-1H-purin-6(7H)-one 2-bromo-1,7-dihydro-6h-purin-6-one 2-bromo-3,7-dihydropurin-6-one 2-bromohypoxanthine 2-bromohypoxanthine 96% 6h-purin-6-one, 2-bromo-1,9-dihydro- 87781-93-9 (C5H7BrN4O) is characterized by an amide group, a hydroxyl group, an ether linkage, 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. 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.
