Compared with other compounds in its class, the molecular weight of 167.37 g/mol gives Samarium(III) hydroxide hydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Samarium(III) hydroxide hydrate (CAS 20403-06-9) is a high-purity analytical reference standard with the molecular formula SmHO and a molecular weight of 167.37 g/mol.
Structurally, Samarium(III) hydroxide hydrate (SmHO) contains an inorganic composition. The molecule exhibits a degree of unsaturation (DBE) of 0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 167.37 g/mol, it falls into the medium-molecular-weight range.
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.
