Chemical Structure
Description
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 supplies 7789-49-3 Nickel dibromide hydrate Nickel(II) bromide trihydrate Nickelous bromide (CAS 7789-49-3), a certified reference material (molecular formula Br2NiH2O, MW 236.52 g/mol) for analytical method development and quality control.
The molecular framework of 7789-49-3 Nickel dibromide hydrate Nickel(II) bromide trihydrate Nickelous bromide (Br2NiH2O) 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.
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.
