The molecular framework of 99A04ICQ3J 7783-85-9 Ferrous ammonium sulfate hexahydrate Ammonium iron(II) sulfate, hexahydrate (2:1:2:6) Sulfuric acid, ammonium iron(2+) salt (2:2:1), hexahydrate Ammonium ferrous sulfate hexahydrate Ferrous ammonium sulfate, hexahydrate Iron ammonium sulfate hydrate Sulfuric acid, ammonium iron(2+) salt, hexahydrate UNII-99A04ICQ3J (HO4SFeH2OH3N) 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.

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

As a certified reference material (CRM), 99A04ICQ3J 7783-85-9 Ferrous ammonium sulfate hexahydrate Ammonium iron(II) sulfate, hexahydrate (2:1:2:6) Sulfuric acid, ammonium iron(2+) salt (2:2:1), hexahydrate Ammonium ferrous sulfate hexahydrate Ferrous ammonium sulfate, hexahydrate Iron ammonium sulfate hydrate Sulfuric acid, ammonium iron(2+) salt, hexahydrate UNII-99A04ICQ3J meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
