Cuproussulfite CAS 35788-00-2

Description

Compared with other compounds in its class, the molecular weight of 143.60 g/mol gives Cuproussulfite distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Cuproussulfite (CAS 35788-00-2), molecular formula O3SCu and molecular weight 143.60 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, Cuproussulfite is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 143.60 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.
