Chemical Structure

Ammonium magnesium sulfate, 98% CAS 20861-69-2 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 Ammonium magnesium sulfate, 98% (CAS 20861-69-2), a certified reference material (molecular formula H2O4SMgH3N, MW 139.41 g/mol) for analytical method development and quality control.

Based on its molecular formula H2O4SMgH3N, Ammonium magnesium sulfate, 98% contains a sulfone group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 139.41 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.

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.
