Chemical Structure

Ceric methanesulfonate CAS 118920-74-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 235.21 g/mol gives Ceric methanesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ceric methanesulfonate (CAS 118920-74-4) is a high-purity analytical reference standard with the molecular formula CeCH3O3S and a molecular weight of 235.21 g/mol.

Owing to a sulfone group, Ceric methanesulfonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 235.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
