Chemical Structure

Praseodymium(III) trifluoromethanesulfonate CAS 52093-27-3 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.

Praseodymium(III) trifluoromethanesulfonate (CAS 52093-27-3) is a high-purity analytical reference standard with the molecular formula CF3O3SPr and a molecular weight of 289.97 g/mol.

Praseodymium(III) trifluoromethanesulfonate (CF3O3SPr) contains a sulfone group, fluorine substitution. It is notably hygroscopic, 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.

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.
