Description

7783-83-7 65390568Z5 Ferric ammonium sulfate Ammonium ferric sulfate Sulfuric acid, ammonium iron(3+) salt (2:1:1), dodecahydrate Iron ammonium sulfate dodecahydrate UNII-65390568Z5 (CAS 7783-83-7) is a high-purity analytical reference standard with the molecular formula HO4SO4SFeH2OH3N and a molecular weight of 284.01 g/mol.

The molecular framework of 7783-83-7 65390568Z5 Ferric ammonium sulfate Ammonium ferric sulfate Sulfuric acid, ammonium iron(3+) salt (2:1:1), dodecahydrate Iron ammonium sulfate dodecahydrate UNII-65390568Z5 (HO4SO4SFeH2OH3N) is characterized by a sulfone group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
