Chemical Information
FooDB NameDimethyl diselenide
DescriptionDimethyl diselenide, also known as (CH3Se)2 or 1,2-dimethyldiselane, belongs to the class of organic compounds known as diselenides. These are organoselenium compounds with the general structure R-Se-Se-R' (R,R' = H or organic moiety). Dimethyl diselenide has been detected, but not quantified in, several different foods, such as green onion, welsh onions (Allium fistulosum), garden onion (var.), onion-family vegetables, and soft-necked garlics (Allium sativum L. var. sativum). This could make dimethyl diselenide a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Dimethyl diselenide.
