Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 209.04 g/mol gives 3-Bromo-1,6-naphthyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Bromo-1,6-naphthyridine (CAS 17965-73-0), molecular formula C8H5BrN2 and molecular weight 209.04 g/mol, is a CATO reference standard with documented purity and traceability.
3-Bromo-1,6-naphthyridine (C8H5BrN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
