Allgemeine Beschreibung
Sodium sulfite is a water-soluble inorganic salt that is commonly used as a reagent for sulfonation and sulfomethylation reactions. Additionally, it is also used as a bleaching, de-sulfurizing, and dechlorinating agent.
Anwendung
Sodium sulfite can be used as:
In combination with carboxylic acids, it forms an effective system for the reductive acylation of aromatic nitro compounds.
- A source of sulfur dioxide (SO2) in the synthesis of 1,4 diazabicyclo[2.2.2]octane bis(sulfur dioxide) (DABSO).
- A reducing agent in the photocatalytic cyclization of 2-isocyanoaryl thioethers to synthesize 2-CF2/CF3-containing benzothiazoles in the presence of Ir-based catalyst.
- A reagent in the selective synthesis of 2-amino-1-iodonaphthalene from 2-naphthylamine in the presence of NaIO3/HCl.
In combination with carboxylic acids, it forms an effective system for the reductive acylation of aromatic nitro compounds.

The coronavirus disease 2019 (COVID-19) pandemic now has >2,000,000 confirmed cases worldwide. COVID-19 is currently diagnosed using quantitative RT-PCR methods, but the capacity of quantitative RT-PCR methods is limited by their requirement of high-level facilities and instruments. We developed and

Organogenesis is well characterized in vertebrates. However, the anatomical and functional development of intracellular compartments during this phase of development remains unknown. Taking an organellogenesis point of view, we characterize the spatiotemporal adaptations of the mitochondrial network during zebrafish embryogenesis.

Nitrone spin traps such as 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) are commonly used for free radical detection. Though proven examples are rare, artifact formation must be considered. For example, the Forrester-Hepburn mechanism yields the same radical adduct as that formed by genuine radical
