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.
Ytterbium(III) sulfate (CAS 13469-97-1), molecular formula O12S3Yb2 and molecular weight 634.27 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, Ytterbium(III) sulfate is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 634.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
