The molecule is an aminouracil that is D-ribitol in which the hydroxy group at position 1 is substituted by the 6-amino group of 5,6-diaminouracil. Early intermediate in bacterial riboflavin synthesis. It has a role as a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a hydroxypyrimidine and an aminouracil. It derives from a ribitol.
