Chemical Structure
Description
The occurrence of Yttrium(III) carbonate is closely related to a carboxylic acid group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Yttrium(III) carbonate (CAS 556-28-5) is a high-purity analytical reference standard with the molecular formula C3O9Y2 and a molecular weight of 357.84 g/mol.
Yttrium(III) carbonate (C3O9Y2) contains a carboxylic acid group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
