Description

General description

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.

Application

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.

Molecular beam mass spectrometry with tunable vacuum ultraviolet (VUV) synchrotron radiation.

Amir Golan et al.

Journal of visualized experiments : JoVE, (68)(68), doi:10-doi:10 (2012-11-15)

Tunable soft ionization coupled to mass spectroscopy is a powerful method to investigate isolated molecules, complexes and clusters and their spectroscopy and dynamics(1-4). Fundamental studies of photoionization processes of biomolecules provide information about the electronic structure of these systems. Furthermore

Ionization of dimethyluracil dimers leads to facile proton transfer in the absence of hydrogen bonds.

Nature chemistry, 4(4), 323-329 (2012-03-23)

Proton transfer is ubiquitous in chemistry and biology, occurring, for example, in proteins, enzyme reactions and across proton channels and pumps. However, it has always been described in the context of hydrogen-bonding networks ('proton wires') acting as proton conduits. Here
