Biochemical research, cosmetics, organic synthesis.
ChEBI: A member of the class of pyrimidones, the structure of which is that of perhydropyrimidine substituted at C-2, -4, -5 and -6 by oxo groups.
Poison by intraperitoneal, intravenous, subcutaneous, and rectal routes. Moderately toxic by ingestion. An experimental teratogen. Other experimental reproductive effects. Mutation data reported. Produces dlabetes in experimental animals. Decomposes in storage to release CO2. Do not store in sealed container. Explodes when heated above 170℃. When heated to decomposition it emits toxic fumes of NOx,.
This sulfhydryl reagent (FW = 142.07 g/mol; CASs = 50-71-5 (free base) and 2244-11-3 (monohydrate)), also named as 2,4,5,6-tetraoxopyrimidine, is an unstable tetraoxopyrimidine that induces diabetes by selectively destroying pancreatic b-cells in laboratory animals upon selective uptake via the GLUT2 transporter. Protocol for Using Alloxan to Induce Diabetes: Step-1: Weigh and measure baseline blood glucose level of mice (Age: 6 weeks or older), adhering to the IACUC Guidelines for Glucose Monitoring of Blood. Step-2: Inject i.v. or i.p. with alloxan (70-90 mg/kg). Step-3: Beginning the day after the alloxan injection, blood glucose levels of each mouse should be checked daily or every other day for 5-7 days. Within 2-3 days after onset of diabetes (as indicated by blood glucose levels), mice should be implanted with an insulin-secreting pellet, when long-term study is necessary. Pellets typically release 0.1 U each 24 hr for >30 days). Mice weighing less than 25 grams require one insulin pellet; larger mice typically receive two insulin pellets to restore normoglycemia.

läuterung methode
Crystallisation from water gives the tetrahydrate. Anhydrous crystals are obtained by crystallisation from acetone, glacial acetic acid or by sublimation in vacuo. [See below and Beilstein 24 H 500, 24 I 428, 24 II 301, 24 III/IV 2137.]
