Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Bromoimidazo[1,5-a]pyrazin-8(7H)-one (CAS 849200-66-4), molecular formula C6H4BrN3O and molecular weight 214.02 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Bromoimidazo[1,5-a]pyrazin-8(7H)-one (C6H4BrN3O) is characterized by an amide group, a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
