Chemical Structure

Samarium(III) chloride hexahydrate CAS 13465-55-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 274.73 g/mol gives Samarium(III) chloride hexahydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Samarium(III) chloride hexahydrate (CAS 13465-55-9), molecular formula Cl3SmH2O and molecular weight 274.73 g/mol, is a CATO reference standard with documented purity and traceability.

Samarium(III) chloride hexahydrate (Cl3SmH2O) contains chlorine 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.
