Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-amino-3-bromo-1,7-naphthyridine-6-carboxylic acid (CAS 2691878-65-4), molecular formula C9H16BrN3O2 and molecular weight 278.15 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-amino-3-bromo-1,7-naphthyridine-6-carboxylic acid (C9H16BrN3O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 278.15 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
