The molecule is a pyrimidone resulting from the formal oxidation of the alcoholic hydroxy group of 5-hydroxymethyluracil to the corresponding aldehyde. It is a major one-electron photooxidation product of thymine in oligodeoxynucleotides. It has a role as a human metabolite and a mutagen. It is a pyrimidone, an aldehyde and a nucleobase analogue. It derives from a 5-hydroxymethyluracil and a thymine.
