Task: Please create a text description for a molecule based on its representation.
Molecule SMILES: O=c1[nH]cc(Br)c(=O)[nH]1
Constraint: Answer the question with complete sentences.
Result: The molecule is a pyrimidine having keto groups at the 2- and 4-positions and a bromo group at the 5-position. Used mainly as an experimental mutagen. It has a role as a mutagen. It is a member of pyrimidines and a nucleobase analogue. It derives from a uracil.
