Verwenden
1,3-Dimethyluracil is suitable reagent used to investigate the steady-state absorption and fluorescence spectra of uracil derivatives. It may be used in the preparation of 2,6-dihydroxynicotinamide.
Definition
ChEBI: 1,3-dimethyluracil is a pyrimidone that is uracil with methyl group substituents at positions 1 and 3. It has a role as a metabolite. It is functionally related to a uracil.
Allgemeine Beschreibung
1,3-Dimethyluracil is a pyrimidine derivative. Stability of the C6-centered carbanions derived from 1,3-dimethyluracil has been investigated in the gas phase and in DMSO and water solutions. The excited state structural dynamics of 1,3-dimethyluracil (DMU) in water and acetonitrile has been studied by resonance Raman spectroscopy. Crystal structure of 1,3-dimethyluracil has been reported. Ultraviolet irradiation of aqueous 1,3-dimethyluracil results in hydration of the 5:6 double bond of the uracil ring to form 1,3-dimethyl-6-oxy-hydrouracil.
Biochem/physiol Actions
1,3-Dimethyluracil is a methyl derivative of uric acid, found occasionally in human urine. 1,3-Dimethyluracil is one of the purine component in urinary calculi. Methylated purines originate from the metabolism of methylxanthines (caffeine, theophylline and theobromine).
Synthese
1,3-Dimethyluracil can be prepared from uracil by methylation under alkaline conditions.
läuterung methode
Crystallise it from EtOH/ether. [Beilstein 24 III/IV 1196.]
