Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 279.08 g/mol gives Ytterbium(iii)oxalatehexahydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ytterbium(iii)oxalatehexahydrate (CAS 30618-32-7), molecular formula YbC2O4H2O and molecular weight 279.08 g/mol, is a CATO reference standard with documented purity and traceability.
Ytterbium(iii)oxalatehexahydrate (YbC2O4H2O) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
