5-Bromouracil Chemical Properties,Usage,Production

Chemical Properties
A major chemical mutagen. Incorporates into DNA, altering base-pair sequencing by replacing thymine
ChEBI: A pyrimidine having keto groups at the 2- and 4-positions and a bromo group at the 5-position.
General Description
White powder.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
A halogenated amide. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).
Health Hazard
ACUTE/CHRONIC HAZARDS: When heated to decomposition 5-Bromouracil emits very toxic fumes of bromide ion and NOx.
Fire Hazard
Flash point data for 5-Bromouracil are not available, but 5-Bromouracil is probably combustible.
