Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 597.99 g/mol gives Bismuth(III) carbonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Bismuth(III) carbonate (CAS 16508-95-5), a certified reference material (molecular formula C3Bi2O9, MW 597.99 g/mol) for analytical method development and quality control.
The molecular framework of Bismuth(III) carbonate (C3Bi2O9) is characterized by a carboxylic acid group, an ether linkage. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
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.
