Ytterbium(III) bromide anhydrous, powder, 99.99% trace metals basis CAS 13759-89-2

Description

Ytterbium(III) bromide anhydrous, powder, 99.99% trace metals basis (CAS 13759-89-2), molecular formula Br3Yb and molecular weight 412.75 g/mol, is a CATO reference standard with documented purity and traceability.

Ytterbium(III) bromide anhydrous, powder, 99.99% trace metals basis (Br3Yb) contains bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
