Chemical Structure

Ammonium iron(II) sulfate CAS 10045-89-3 chemical structure

Description

The occurrence of Ammonium iron(II) sulfate is closely related to a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ammonium iron(II) sulfate (CAS 10045-89-3), molecular formula O4SFeH4NH2O and molecular weight 187.96 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula O4SFeH4NH2O, Ammonium iron(II) sulfate contains a sulfone group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 187.96 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
