Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6-Bromopyrrolo[2,1-f][1,2,4]triazin-4(3H)-one (CAS 888721-83-3) is a high-purity analytical reference standard with the molecular formula C6H6BrN3O and a molecular weight of 216.04 g/mol.
6-Bromopyrrolo[2,1-f][1,2,4]triazin-4(3H)-one (C6H6BrN3O) contains an amide group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
