Chemical Structure
Description
Manganese(II) sulfate tetrahydrate (CAS 10101-68-5), molecular formula H2O4SMnH2O and molecular weight 171.03 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, Manganese(II) sulfate tetrahydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 171.03 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.
