General description

Manganese (II) sulfate monohydrate is a safe and inexpensive catalyst used in organic synthesis. Additionally, it is used to prepare manganese dioxide and manganese.

Application

Manganese (II) sulfate monohydrate is used:
  • As a catalyst in the synthesis of heterocyclic compounds such as benzo-2-pyrones and benzopyrazines.
  • To prepare cathode material magnesium manganese spine (MgMn2O4) by coprecipitation method.

Two abiotic stress-inducible upstream regulatory sequences (URSs) from rice have been identified and functionally characterized in rice. NBS-Str1 and BLEC-Str8 genes have been identified, by analysing the transcriptome data of cold, salt and desiccation stress-treated 7-day-old rice (Oryza sativa L.

Humans exposed to excess levels of manganese (Mn(2+)) express psychiatric problems and deficits in attention and learning and memory. However, there is a paucity of knowledge on molecular mechanisms by which Mn(2+) produces such effects. We now report that Mn(2+)

Neurotoxicity is linked with high-dose manganese inhalation. There are few biomarkers that correlate with manganese exposure. Blood manganese concentrations depend upon the magnitude and duration of the manganese exposure and inconsistently reflect manganese exposure concentrations. The objective of this study

Manganese neurotoxicity in humans is recognized as a form of parkinsonism with lesions occurring predominantly within the globus pallidus, subthalamic nucleus, putamen, and caudate nucleus. This study evaluated dopamine, 3,4-dihydroxyphenylacetic acid, homovanillic acid, serotonin, norepinephrine, 5-hydroxyindoleacetic acid, gamma-aminobutyric acid (GABA)
