Dimethyldiselenide Usage And Synthesis
Chemical Propertiesorange liquid with a very unpleasant smell
UsesDimethyl diselenide is a powerful reagent used for identification of distonic radical cations
DefinitionChEBI: Dimethyl diselenide is an organoselenium compound that is diselane covalently bound to two methyl groups. It has been detected in onion-family vegetables and soft-necked garlics. It induces ER stress and toxic protein aggregation in the budding yeast, S. cerevisiae and used as a reagent to identify distonic radical cations. It has a role as a bacterial metabolite, a mammalian metabolite, a plant metabolite and a human xenobiotic metabolite.
General DescriptionDimethyl diselenide is a volatile selenium species and its determination in biological samples by HPLC-inductively coupled argon plasma mass spectrometry was reported. Selenium alkylation with dimethyl diselenide was reported by solid-phase microextraction gas chromatography-mass spectrometry.
