Chemical Structure

Iron(II) sulfate dihydrate CAS 10028-21-4 chemical structure

Description

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.

CATO supplies Iron(II) sulfate dihydrate (CAS 10028-21-4), a certified reference material (molecular formula H2O4SFeH2O, MW 171.93 g/mol) for analytical method development and quality control.

Owing to a sulfone group, Iron(II) sulfate dihydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 171.93 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.
