Application
Selenourea [(SeC(NH2)2)] has been used as a selenium (Se) precursor for the insertion of Se into protein crystals.
It can also be used as a reagent to synthesize:
It can also be used as a reagent to synthesize:
- Selenazoles from α -bromo ketones presence of β -cyclodextrin.
- Symmetrical diaryl selenides by C-Se cross coupling reaction in presence of coper oxide nanaoparticles as a catalyst.

We report a general strategy for obtaining high-quality, large-area metal-chalcogenide semiconductor films from precursors combining chelated metal salts with chalcoureas or chalcoamides. Using conventional organic solvents, such precursors enable the expeditious formation of chalco-gels, which are easily transformed into the

Selenium (SC) toxicity was experimentally induced in male buffalo calves following repeated oral administration of 0.3 mg selenourea/kg (providing 0.19 mg/Se kg) for 75 d. On the basis of the major toxic effects produced in the experimental animals, 10 additional
