Application

Iron(II) chloride tetrahydrate can be used as a catalyst in the:

Solvent-free Ritter reaction of nitriles with various halohydrocarbons to synthesize N-substituted amides.
Synthesis of ketones via indirect hydration of alkynes.
Stereoselective reduction of α, β-unsaturated carbonyl compounds to the corresponding saturated alcohols in the presence of lithium and DTBB.

It can also be used as a precursor to prepare iron-bisphosphine complex, which can be used to catalyze Kumada-Tamao-Corriu coupling.

Labeling of the pathogenic bacterium Staphylococcus aureus with gold or ferric oxide-core nanoparticles highlights new capabilities for investigation of host-pathogen interactions.

Maren Depke et al.

Cytometry. Part A : the journal of the International Society for Analytical Cytology, 85(2), 140-150 (2013-12-19)

Throughout the world, infections caused by bacteria such as Staphylococcus aureus are a major cause of morbidity and mortality. In order to gain some understanding of the complicated physiological link between host and pathogen, modern techniques such as confocal microscopy

Ferrous and Ferric Ion-Facilitated Dilute Acid Pretreatment of Lignocellulosic Biomass under Anaerobic or Aerobic Conditions: Observations of Fe Valence Interchange and the Role of Fenton Reaction.

Hui Wei et al.

Molecules (Basel, Switzerland), 25(6) (2020-04-05)

Ferrous ion co-catalyst enhancement of dilute-acid (DA) pretreatment of biomass is a promising technology for increasing the release of sugars from recalcitrant lignocellulosic biomass. However, due to the reductive status of ferrous ion and its susceptibility to oxidation with exposure

Synthesis of Fe₃C@C from Pyrolysis of Fe₃O₄-Lignin Clusters and Its Application for Quick and Sensitive Detection of PrPSc through a Sandwich SPR Detection Assay.

Chenglong Yuan et al.

International journal of molecular sciences, 20(3) (2019-02-13)

The prion protein (PrPSc) has drawn widespread attention due to its pathological potential to cause prion diseases. Herein, we successfully synthesized Fe₃C@C by carbonizing Fe₃O₄-lignin clusters, which were prepared through a facile hydrogen bonding interaction between ≡Fe-OH and hydroxyl groups
