User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a member of the class of condensed ureas that is urea in which each of the amino groups has had one of the attached hydrogens replace by a carboxy group. It derives from a urea-1-carboxylic acid and a carbamic acid. It is a conjugate acid of a 1,3-dicarboxyurea(2-).
Assistant: This is a molecule that fits your description: O=C(O)NC(=O)NC(=O)O
