Chemical Structure
Description
Ytterbium(III) Oxalate Decahydrate (CAS 51373-68-3), molecular formula C6O12Yb2H2O and molecular weight 628.17 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, Ytterbium(III) Oxalate Decahydrate is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 628.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
