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-Amino-1-(2-bromophenyl)-1H-pyrazole-4-carboxamide (CAS 1552887-22-5) is a high-purity analytical reference standard with the molecular formula C10H9BrN4O and a molecular weight of 281.11 g/mol.
5-Amino-1-(2-bromophenyl)-1H-pyrazole-4-carboxamide (C10H9BrN4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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.
