Ammonium iron(II) sulfate hexahydrate (CAS 7783-85-9)

Ammonium iron(II) sulfate hexahydrate or Mohr′s Salt is often employed as an analytical standard, and has been used in a variety of other applications from nanomaterials to general redox reactions. This product is much less affected by oxygen in the air than iron(II) sulfate (sc-228358), making it more desirable for titration purposes, where iron(II) might be oxidized to iron(III). The oxidation of iron(II) to iron(III) is pH dependent, and the reaction occurs more rapidly at higher pH Mohr′s Salt lowers the pH of solutions slightly, thereby preventing oxidation from occurring. The significance of ammonium iron(II) sulfate hexahydrate extends to scientific research, serving as a vital reagent in diverse biochemical and physiological experiments. It plays a pivotal role in studying the impact of iron on biological systems, conducting iron detection in biological samples, and catalyzing organic synthesis reactions. Additionally, it finds application in the analysis of proteins, lipids, carbohydrates, and other biomolecules. By acting as a proton donor, it influences the pH of its surroundings, thereby affecting the activity of enzymes and other proteins. Furthermore, it acts as a Lewis acid, accepting electrons from other molecules and thereby influencing the structure and reactivity of the involved molecules. Ammonium iron(II) sulfate hexahydrate, or ferrous sulfate, represents a versatile compound with a wide range of applications in scientific exploration, industrial processes, and medical contexts. Its ability to modulate pH and interact with various molecules allows for valuable insights and advancements in numerous fields of study.
