white to cream fine crystalline powder
Verwenden
2-Thiouracil has been used in the synthesis and characterization of silver colloid and film substrates and their applications in surface-enhanced Raman scattering (SERS)
Definition
ChEBI: A nucleobase analogue that is uracil in which the oxo group at C-2 is replaced by a thioxo group.
Sicherheitsprofil
Moderately toxic by
ingestion. Human teratogenic effects by
unspecified routes: developmental
abnormalities of the central nervous system,
craniofacial area, and endocrine system.
Human reproductive effects by unspecified
route: effects on newborn, including viabllity
index changes. Experimental teratogenic
effects. Other experimental reproductive
effects. Questionable carcinogen with
experimental neoplastigenic and tumorigenic
data. Mutation data reported. When heated
to decomposition it emits very toxic fumes
of NOx and SOx. Used in the treatment of
hyperthyroidism, angina pectoris, and
congestive heart failure. See also
MERCAPTANS and KETONES.
