1,1-DIMETHYL-2-SELENOUREA Chemical Properties,Usage,Production

Chemical Properties

light brown to grey crystalline powder

Uses

1,1-Dimethyl-2-selenourea was used as precursor to synthesize CdSe quantum dots in aqueous solution under simultaneous illumination with a diode-pumped solid state green laser and a Xe-Hg lamp.

General Description

One-electron oxidation of 1,1-dimethyl-2-selenourea (1,1′-dimethyl-2-selenourea) by hydroxyl radicals, one-electron-specific oxidants, was studied using pulse radiolysis technique.
