Compared with other compounds in its class, the molecular weight of 492.43 g/mol gives Niobium(V) bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Niobium(V) bromide (CAS 13478-45-0), molecular formula Br5Nb and molecular weight 492.43 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Niobium(V) bromide (Br5Nb) is characterized by bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Niobium(V) bromide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
