Chemical Structure
Description
CATO supplies 252976-51-5 Trifluoromethanesulfonic acid ytterbium salt Yb(OTf)3 Ytterbium(III) triflate Ytterbium(III) trifluoromethanesulfonate hydrate (CAS 252976-51-5), a certified reference material (molecular formula C3F9O9S3YbH2O, MW 638.25 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, an ether linkage, fluorine substitution, 252976-51-5 Trifluoromethanesulfonic acid ytterbium salt Yb(OTf)3 Ytterbium(III) triflate Ytterbium(III) trifluoromethanesulfonate hydrate is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 638.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
