5,6-DIHYDROURACIL Usage And Synthesis
Chemical Propertieswhite to light beige crystalline powder
UsesImpurity of Uracil.
Uses5,6-Dihydrouracil acts as an intermediate in the catabolism of uracil.
UsesDihydrouracil has been used as a standard for ureido group in the colorimentric assay of transfer ribonucleic acid (tRNA).
General DescriptionDihydrouracil (DiHU) is a minor base found in transfer ribonucleic acid (tRNA). It is similar to uracil with the only exception that the C5-C6 bond is saturated. It crystallized in the monoclinic system with space group P21/C. Its crystalline structure has been analyzed. Its generation from L-cysteine and uracil via photochemical addition has been described.
