Chemical Structure

Gadolinium(III) sulfate CAS 155788-75-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 253.31 g/mol gives Gadolinium(III) sulfate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Gadolinium(III) sulfate (CAS 155788-75-3) is a high-purity analytical reference standard with the molecular formula GdO4S and a molecular weight of 253.31 g/mol.

Structurally, Gadolinium(III) sulfate (GdO4S) contains a sulfone group. 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 253.31 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.
